Biography of Arthur Miller, Major American Playwright

Biography of Arthur Miller, Major American Playwright Arthur Miller (October 17, 1915–February 10, 2005) is considered one of the greatest playwrights of the 20th century, having created some of Americas most memorable plays over the course of seven decades. He is the author of Death of a Salesman, which won the 1949 Pulitzer Prize in drama, and The Crucible.  Miller is known for combining social awareness with a concern for his characters’ inner lives. Fast Facts: Arthur Miller Known For: Award-winning American playwrightBorn: October 17, 1915 in New York CityParents: Isidore Miller, Augusta Barnett MillerDied: Feb. 10, 2005 in Roxbury, ConnecticutEducation: University of MichiganProduced Works: All My Sons, Death of a Salesman, The Crucible, A View From the BridgeAwards and Honors: Pulitzer Prize, two New York Drama Critics Circle Awards, two Emmy Awards, three Tony AwardsSpouse(s): Mary Slattery, Marilyn Monroe, Inge MorathChildren: Jane Ellen, Robert, Rebecca, DanielNotable Quote: Well, all the plays that I was trying to write were plays that would grab an audience by the throat and not release them, rather than presenting an emotion which you could observe and walk away from. Early Life Arthur Miller was born on October 17, 1915, in Harlem, New York to a family with Polish and Jewish roots. His father Isidore, who came to the U.S. from Austria-Hungary, ran a small coat-manufacturing business. Miller was closer to his mother Augusta Barnett Miller, a native New Yorker who was a teacher and an avid reader of novels. His fathers company was successful until the Great Depression dried up virtually all business opportunities and shaped many of the younger Millers beliefs, including the insecurity of modern life. Despite facing poverty, Miller made the best of his childhood. He was an active young man, in love with football and baseball. When he wasn’t playing outside, Miller enjoyed reading adventure stories. He also kept busy with many boyhood jobs. He often worked alongside his father; other times, he delivered bakery goods and worked as a clerk in an auto parts warehouse. College After working at several jobs to save money for college, in 1934 Miller left the East Coast to attend the University of Michigan, where he was accepted into the school of journalism. He wrote for the student paper and completed his first play,  No Villain, for which he won a university award. It was an impressive beginning for a young playwright who had never studied plays or playwriting. Whats more, he had written his script in just five days. He took several courses with Professor Kenneth Rowe, a playwright. Inspired by Rowes approach to constructing plays, after graduating in 1938, Miller moved back East to begin his career as a playwright. Broadway Miller wrote plays as well as radio dramas. During World War II, his writing career gradually became more successful. (He couldnt serve in the military because of a football injury.) In 1940 he finished The Man Who Had All the Luck, which reached Broadway in 1944 but closed after only four performances and a pile of unfavorable reviews. His next play to reach Broadway came in 1947 with All My Sons, a powerful drama that earned critical and popular praise and Millers first Tony Award, for best author. From that point on, his work was in high demand. Miller set up shop in a small studio that he had built in Roxbury, Connecticut, and wrote Act I of  Death of Salesman  in less than a day. The play,  directed by  Elia Kazan, opened on February 10, 1949, to great acclaim and became an iconic stage work, earning him international recognition. In addition to the Pulitzer Prize, the play won the New York Drama Critics Circle Award and swept all six of the Tony categories in which it was nominated, including best direction, best author, and best play. Communist Hysteria Since Miller was in the spotlight, he was a prime target for the House Un-American Activities Committee (HUAC), led by Wisconsin  Sen.  Joseph McCarthy. In an age of anti-communism fervor, Miller’s liberal political beliefs seemed threatening to some American politicians, which is unusual in retrospect, considering that the Soviet Union banned his plays. Miller was summoned before the HUAC and was expected to release names of any associates he knew to be communists. Unlike Kazan and other artists, Miller refused to give up any names. â€Å"I don’t believe a man has to become an informer in order to practice his profession freely in the United States,† he said. He was charged with contempt of Congress, a conviction that was later overturned. In response to the hysteria of the time, Miller wrote one of his best plays, The Crucible. It is set during another time of social and political paranoia, the Salem Witch Trials, and is an insightful criticism of the phenomenon. Marilyn Monroe By the 1950s, Miller was the most recognized playwright in the world, but his renown wasn’t only because of his theatrical genius. In 1956, Miller divorced Mary Slattery, his college sweetheart with whom he had had two children, Jane Ellen and Robert. Less than a month later he married actress and Hollywood sex symbol  Marilyn Monroe, whom hed met in 1951 at a Hollywood party. From then on, he was even more in the limelight. Photographers hounded the famous couple and the tabloids were often cruel, puzzling over why the â€Å"world’s most beautiful woman† would marry such a â€Å"homely writer. Author  Norman Mailer  said their marriage represented the union of the Great American Brain and the Great American Body. They were married for five years. Miller wrote little during that period, with the exception of the screenplay for  The Misfits  as a gift for Monroe. The  1961 film,  directed by  John Huston, starred Monroe,  Clark Gable,  and  Montgomery Clift. Around the time the  film was released, Monroe and Miller divorced.  A year after divorcing Monroe (she died the following year), Miller married his third wife, Austrian-born American photographer Inge Morath. Later Years and Death Miller continued to write into his 80s. His later plays didnt attract the same attention or acclaim as his earlier work, though film adaptations of The Crucible and Death of a Salesman kept his fame alive. Much in his later plays dealt with personal experience. His final drama, Finishing the Picture, recalls the turbulent last days of his marriage to Monroe. In 2002, Millers third wife Morath died and he soon was engaged to 34-year-old painter Agnes Barley, but he became ill before they could marry. On February 10, 2005- the 56th anniversary of the Broadway debut of  Death of a Salesman- Miller died of heart failure  at his home in Roxbury, surrounded by Barley, family, and friends. He was 89 years old. Legacy Millers sometimes bleak view of America was shaped by his and his familys experiences during the Great Depression. Many of his plays deal with the ways capitalism affects the lives of everyday Americans. He thought of theater as a way to speak to those Americans: The mission of the theater, after all, is to change, to raise the consciousness of people to their human possibilities, he said. He established the Arthur Miller Foundation to help young artists. After his death, his daughter Rebecca Miller focused his mandate on expanding the arts education program in New York City public schools. In addition to the Pulitzer Prize, Miller won two New York Drama Critics Circle Awards, two Emmy Awards, three Tony Awards for his plays, and a Tony Award for Lifetime Achievement. He also received the John F. Kennedy Lifetime Achievement Award and was named Jefferson Lecturer for the National Endowment for the Humanities in 2001. Sources Arthur Miller Biography.

Worst Super Glue Accidents

Worst Super Glue Accidents Super glue is an amazing adhesive. Its so amazing that its easy to accidentally glue something you didnt want glued! Have you ever super glued something by mistake or even meant to glue it and then regretted it? What did you end up doing to fix the problem? I asked readers to share their stories. Here is what they wrote... Awkward I remember this one time I was sitting next to my friend in science class, Justin, and I smashed a glass container. My teacher gave me super glue because apparently they were low on glass test tubes so I had to glue it back together, but what I didnt realize is that I had glue on my hands and when I reached to put the glass test tube back in the tray I accidentally touched my friends hand. I dont know why but we literally couldnt move our hands apart so because I was embarrassed to tell a teacher about it, I had to sit through 3 classes (1 hour each) with my hand stuck to Justins. After that we had to walk to my house, un-stick our hands and then Justin had to walk home. The next day was so awkward. - Amy Thaitene Going Crazy Glued My Teeth About 6 months ago I did the worst thing Ive ever done to my body I super glued my teeth nothing actually happened or I didnt really notice but the last month I started with the little peeling and now I noticed that my 80 percent of my teeth covered in a layer of glue. I have never experienced anything like this in my life and it is hell. - super tethed How to Remove Super Glue from Other Stuff Usually you should apply acetone to a cotton ball and apply to the doorknob areas where they are glued. Then wait a bit. The acetone should seep through the closed spaces and remove it so you can pop it off. - Alison Super Glue Issue I used a super glue type product to glue the temp control knob in my car that came off. Now the knob wont turn at all. How can I pop the knob off, even though it has been super glued? - Guest Jeff Franklin Carpet vs Hardwood Our 3 year old daughter glued our pet cats paws to the carpet so that he would stay! Thank goodness it simply took a few snips of the scissors to free Smokey. - Shes2cute Pants, Man! Literally half an hour ago I was super gluing together my broken binder and the glue was being stubborn, so I squeezed a little harder and half of the tube came out and instantly dried - on my pants. It soaked through and stuck to my leg, so Im now trying to do the whole mayonnaise thing because I have mayo. Hope it works. - juantacos Nail Fail Attempting to glue on falsies. All going well put the glue on the then I went to put it on my finger, but I had glued it to my fingers from holding it wrong then pulled it off. Glue went all over my face. Scared me half to death. Hurt so much! - noname Lol I hate super glue. Never used it but Im scared so I wear full protection. - lol Super Glued My Eye In a college art class I couldnt get the superglue out of the tube so squeezed it real hard and it shot up into my eye. I pried my eye until it opened up again and work at getting the glue of the skin and lashes. It was hard though because it was also caked all over my fingers. Luckily I think I must have blinked my eyes just as it hit my eye because it seemed to only be on the outside. I ripped some eyelashes out and had to wait and work at the glue for it all to come off. But after that experience, I feel pretty stupid, who gets super glue in their eye in college? - johannanow Mayonnaise NOT Acetone I glued 3 fingers with Super Glue! Soak fingers in a bowl of mayonnaise for 20 minutes and the glue will crystallize and crumble off. No fuss, no muss... no acetone! - Papa J Pepper I JUST GOT SOME SUPERGLUE ON MY FINGER (DIDNT KNOW IT WAS ON THERE). ANYWAY, PUT MY FINGER NEXT TO MY NOSE, AND. OF COURSE IT LANDED ON MY FACE WHICH WE ALL KNOW IT DRIED QUICKLY. YOU KNOW WHAT I GOT IT OFF WITH I PUT SOME SIMPLE VASELINE ON IT AND LET IT SIT FOR ABOUT 10 MINUTES THEN I RUBBED IT BRISKLY AND IT CAME RIGHT OFF! THATS MY INVENTION FOR THE DAY! - JC Super Glue Prevention to Get Smeared Prevention to get smeared by Super Glue is better than for the exercises for removal. Apply generously any edible oil (cooking oil) -groundnut/peanut/sunflower/soybean whatever is available on both of you hands and wait for a few minutes. Wipe of you hands with waste cotton/cloth/tissue paper. use safety goggle/zero glass to protect your eyes. Super glue will not stubbornly act on your skin. You can wash off your hand with any soap and warm water. - D.K.Sarkar Never Using Super Glue Again I squirted super glued my eye years back when I was trying to fix a split in a manicured finger nail. The glue wouldnt come out of the tube (it was like a toothpaste tube), so I gave the tube a good squeeze. The came squirting out the back, crimped end and into one of my eyes and under it. It stung and my first thought was will I be blinded? Luckily, my tearing eye cleared away the glue that was on my eye ball, but I could not get the glue from the skin under my eye without very gently using nail polish remover and a cotton swab multiple times over a couple of days and it looked like I had a wrinkled rash under the eye until I get the last of it off. - ShelleyElmblad The Things We Do for Beauty... Yes, Ill admit it. I did super glue my eyeball. Actually, it was the cyanoacrylate glue that comes with single false eyelashes. My aim was not so great and I stuck an eyelash to my eyeball. I know, it sounds horrible, but it wasnt so bad. The glue did sting a little, but it loosened on its own in a couple of minutes. I wouldnt recommend it though. - gemdragon

Haiti Development Research Paper Example | Topics and Well Written Essays - 750 words

Haiti Development - Research Paper Example Though independent long before, the economy of the country is still in the struggling phase. According to the recent reports, the per capita income of the country in 2009 has been a meager $ 790 that tantamounts to a nominal sum of $ 2 per day per person. Having such poor performance on the economic front, the country has almost 80% of the population below the poverty level while only half the population is believed to be literate. The country is basically an agricultural nation but unlike many of the other nations of the world, agricultural population of Haiti does not have access to the modern means and techniques of agriculture. This is prevalent as while more than 65% of the population is engaged with agriculture, the profession yields even less than 30% of the GDP for the country (Foreign & Common Wealth Office, â€Å"Haiti†). The extreme poor performance of the economy of Haiti has its linked consequences like that of underprivileged human resource development and that of topping the list of corruption. The other prominent demerit of the country has been the concentration of wealth. It is perceived that top 1% of the population controls almost half of the nation’s wealth. The condition of the economy is also depicted by the prime source of earning for the government which has been the external debt for years now. In 2005, a new born baby in Haiti had a liability of US $ 169 (because of external debt) though recently the international bodies like that of IMF and World Bank have written off the external debt (IMF, â€Å"Haiti: Enhanced Initiative for Heavily Indebted Poor Countries — Completion Point Document†). The poor country of Haiti has been further affected by the disastrous environment time and again. Though the country was blessed with deep forest and had rich flora and fauna, the diminishing economy of the nation has resulted in cutting of most of such

Fiat Business Case Essay Example | Topics and Well Written Essays - 1250 words

Fiat Business Case - Essay Example Additionally, it was also felt that the company was very late in addressing the quality issues related to its products. This delay in improving the quality of its products dissuaded customers from buying Fiat’s cars. This was also a major reason because of which Fiat was not able succeed in the American car market despite its affordability and this also lead the company to withdraw itself from the American car market. Towards the end of 1990s, the company also experienced a financial crunch due to its diversification measures. The acquisitions made by Fiat Auto during the period contributed to its problem since the performance of some of the acquired businesses was rather disappointing and additionally they also resulted in added costs for the company. Another factor responsible for this situation of the company was that the company bought a few firms when it was at the top of its business cycles and consequently had to shell out a lot of money to acquire them. The debts of Fiat were largely the result of such acquisitions made by the Italian automobile giant. Factors that are related to planning and control play a vital role in the decline of the Italian automotive giant. The role played by the R&D department is to be seriously taken into account while discussing about the crisis or performance decline of Fiat. The reason behind this can be described as the â€Å"supremacy† of the Engineers at the R&D wing. The most serious problem recognized is the â€Å"supremacy† of Engineering over customers’ needs. The requests of Marketing are often rejected because considered as wrong from an engineering perspective. This is an issue of huge concern because Marketing is the one that gives information about customers’ needs, expectations, and market trends. Whenever a company’s value chain is observed, equal

Comcast Research Paper Example | Topics and Well Written Essays - 750 words

Comcast - Research Paper Example The company’s growth has considerably increased for the last few years. Secondly, DirecTV is a provider of American direct broadcast satellite service in California. The DirecTV’s satellite service was launched in 1994; it engages in the transmission of digital satellite television and audio mainly in the United States and Latin America. DirecTV had 19.2 million subscribers at the end of 2010. The third organization of choice, The Verizon Communications engages in broadband and telecommunications business globally; it is an element of the Dow Jones Industrial Average. Financial position of Comcast While conducting a thorough scrutiny on the financial statements of the Comcast during the past several years, it is clear that the company is rapidly moving towards economic expansion. In 1995, the book value of a company’s share was $8.19 and it reached $15 per share in 2009. It shows that the company could double its price per share during this period of 14 years. An increase in share price is the direct indication of increased market demand for the Comcast’s services. ... It has been identified that Comcast’s net profit margin rose from 4.2% in 1999 to 8.4% in 2009 (Comcast). During this same time span, the firm’s operating margins and return on equity notably improved. Finally, the Comcast’s total selling/general/administrative expenses climbed from $5,075 billion in 2006 to $8,091 billion in 2010 (Comcast). Financial comparison As in the case of Comcast, DirecTV also shows a rampant increase in its total revenues during the last few years. The DirecTV’s total revenue indicates the figure $24,102 billion while it was $21,565 billion in 2009 (DirecTV). In contrast, Verizon’s total revenue faced a decline in 2010; it fell from $107,808 billion in 2009 to $106,565 billion in 2010. As a result, the Verizon also faced a decline in net profit by $2345 billion (Verizon). The Verizon’s financial statement reflects that its economical position is not satisfactory. The company’s net income gradually diminished a nd the Verizon even suffered a net a loss by $2,193 billion in 2008. The poor financial performance of the Verizon Communication in 2008 can be directly attributed to its increased total of selling/general/administrative expenses ($41,517 billion) (Verizon). On the other hand, it seems that the DirecTV reflects a better financial performance during the past several years except in 2009. The DirecTV’s net incomes were $1,420; $1,451; $1,521; $942; and $2,198 billions respectively in 2006, 2007, 2008, 2009, and 2010. Although, the DirecTV struggled with $942 billion net income in 2009, it could effectively resurrect in 2010 by increasing the net income by $1,256 billion (DirecTV). Evidently differences exist in the financial statement composition of these three

Alternative Materials For Aircraft Wings

Alternative Materials For Aircraft Wings For this report I have chosen to research and find an alternative material for aircraft wings, currently the material being on aircraft wings is aluminium alloy series 2000, specifically 2024 as this alloy consists of about 4.5% copper, 1.5% magnesium, 0.6% manganese with traces of other specific elements permitted, and the remainder aluminium.  [1]  The alternative material must be capable of achieving all the characteristics of aluminium alloy 2024, yet be light in weight and preferably within the cost region of materials currently used. Aims and objectives The aim of this report is discuss how alternative materials can be produced to manufacture a new lighter aircraft wing. In order to do this the new material must be capable of withstanding high stress loads, be light in weight and preferably low in cost. Also, manufacturing technique must be looked into with respect to machinability of material, cost of machines, and repairing material. Current materials in use Aluminium alloy 2024 This is used in the aviation industry as it has the right properties required to meet the demands. The principle alloying element used is copper. This alloy requires solution heat treatment to obtain its best properties when the alloy has been through the solution heat treatment process the mechanical properties become similar to and sometimes exceed those of mild steel. To further increase the mechanical properties of aluminium alloy 2024, an artificial ageing process is used; this method of treatment increases the yield strength. Once the aluminium alloy has been made, the properties obtained are high strength to weight ratio, as well as good fatigue resistance. Though this is not wieldable and has average machinability. Due to poor corrosion resistance the alloy is usually cladded with pure aluminium, however, this does usually reduce the fatigue resistance of the alloy. Aluminium alloy 2024 consists of about 4.5% copper, 1.5% magnesium, 0.6% manganese with traces of other specific elements permitted and the remainder is aluminium. Mechanical properties of aluminium 2024 The mechanical properties of 2024 depend on the temper of the material. 2024-0 This form of alloy has no heat treatment (annealed). It has an ultimate tensile strength of 207-220 MPa more yield strength of 96 MPa. This form of alloy also has an elongation factor of 10-25%. 2024-T3 This form of alloy has been solution treated and strain hardened with the ultimate tensile strength is between 400-427 MPa and yield strength of 369-276 MPa with an elongation of 10-15%. New materials to consider Titanium This metal has a high strength to weight ratio, a relative density of 4.5 which is 60% heavier than aluminium however, it is twice as strong. Titanium has excellent corrosion resistance properties this is due to the oxide film which forms. Titanium is not normally susceptible to stress, fatigue, intergranular or galvanic corrosion, putting or localised attack. However, under certain circumstances it will burn in air, therefore in order to prevent a reaction with oxygen or nitrogen it may be treated with chloride gas in order to form a protective coating of titanium dioxide. Titanium normal alloying elements include aluminium, chromium, iron, manganese, molybdenum and vanadium. Titanium and its alloys are classed in 3 categories: Alpha (A) Wieldable, tough, strong both hot and cold and resistant to oxidisation. Beta (B) Excellent bend ductility, strong both hot and cold however vulnerable to contamination. Combined (C) Combination of alpha and beta with comprised performance, strong cold and warm but weak when hot, excellent forgability, good bendibility moderate contamination resistance. The melting point of titanium is 1668 degrees Celsius and has low thermal conductibility and a low co efficient of expansion. Its high temperature properties are however disappointing.; the ultimate yield strength falls rapidly above 425 degrees Celsius and atmospheric oxygen and nitrogen absorbent above 540 degrees Celsius makes the metal brittle and worthless after a long term exposure. Therefore it is only useful for short durations, high temperatures applications where strength is not important such as air conditioned firewalls. When working with titanium extra care must be taken when making due to its extreme work hardening properties. E.g. centre drilling should be used prior to drilling as centre punch this material would harden the metal, causing difficulty when drilling. Composite A composite material consists of 2 or more different materials whose mechanical properties compliment each other although maintain their separate identities, unlike alloy. The reason the composite materials are used on an aircraft and their strength to weight ration and corrosion resistance. Reinforced plastics are much lighter than metals. If the metal part can be as much as 25 times heavier than an equivalent composite part, however that composite part must be as strong and durable as the original. Therefore reinforced plastics must have very good strength, stiffness and impact resistance. Strength- this is the ability of a material to support a load without breaking. Stiffness- this is the ability of material to support a load without bending too much. Impact- this is the ability of a material to withstand resistance impact without shattering. The types of composites to consider for this project would be, Glass reinforced plastic Aramid fibres Carbon fibres Glass Reinforced Fibres (GRFs) Glass Reinforced Fibres are currently used on aircraft for radomes (the fairings which cover radar antennas and must be transparent to radio waves). The fibreglass is used for reinforcement for thermosetting resins in aircraft applications is available as a cloth in many different weights and weaves as a loose of fibreglass. When combined, the fibre and resin GRF. For applications which require the most strength it is necessary to use uni-directional glass tape. Whereas woven glass cloth has better shaping properties and high strength. There are many types of Glass Reinforced Fibres used, and the main ones used in the aviations industry are: A Glass- standard soda glass has a high alkaline content which absorbs moisture which increases degrading of material and corrosion. This leaks to resins deterioration. The main use for this is for windows. C Glass- high resistance to corrosive material. It is normally produced and used only as a surface matt to reduce cost. D Glass- with a low di-electric constant this type of glass is used for radomes. E Glass- with low alkali content and good resin adhesion properties where used in air conditioning. Styles of woven fabric The most common style used is the plain weave where; the warp and wraft threads cross alternately. The strength of woven fabrics in comprised due to the severe pre- buckling already present in the fabric. Fibres usually produce their greatest strength when they are perfectly straight. Due to the high frequency of over and under weaving of the threads the strength is reduced; in plain weave. This is where twill weave and satin weave come in as it is high pliable and stronger than the plain weave style. This table shows a comparison of the properties of common weaves used in aerospace: Stability ability of the weave to hold together when cut. Drape ability of the cloth to follow a complex shape. Porosity an indication of the amount of resin required to thoroughly wet the cloth. Smoothness surface finish of the cloth. Balance a comparison between the warp and weft direction. Symmetry the weave pattern. Crimp an indication of the amount or frequency of bend in the yarns.  [5]   Aramid fabrics Aramid fibres also known as Kevlar is made from aromatic polyamide, a type plastic similar to nylon. The properties include; High tensile strength and resistance to impact of any composite reinforcing fibre. Stiffer than glass but only half as stiff as carbon fibre. 40% lighter than glass fibre 10x stronger than aluminium Up to 400% stronger than comparable glass reinforced laminates. Up to 20% stronger than comparable carbon enforced laminates Aramid fibres have very high impact strength with the damage confined to small areas. Due to this, Aramid can be used in areas prone to stone and runaway debris damage, so this could be useful for use on aircraft wings. However, Aramid fibres have lower compression strength than carbon, it absorbs moisture more readily than glass or carbon, also Aramid deteriorates in strong sunlight. Aramid is more difficult to cut, drill, sand then either glass or carbon, it also does not give clean edges. Aramid fibres do not resist flame well and burn through more quickly than other fibres. Resin adhesion is also lower, delamination being one of the ways in which it absorbs impact energy. Carbon fibres Carbon fibres are made from carbon and are black in colour carbon fibres were first used on air conditioning in the 1980s. The fibres are manufactures by the controlled heating of POLYCRILONITRILE (PAN), polythene or rayon fibres are pre-oxidised at 200-300 degrees Celsius for 1 hour then carbonised at 1200 degrees the graphitised at 2000 to 3000 degrees Celsius. This removes the hydrogen, nitrogen and oxygen leaving long oriented carbon chains. The fibres are sometimes surface oxidised, this improves their building characteristics and sized, this then reduces the build up of static electricity and improves bonding. Carbon fibres are available in forms basic groups and produced at different graphitisation temperature and defined by tensile modules Standard modules (high strength) Intermediate modules (high stiffness) High modulus Ultra high modulus. All forms of carbon fibre are stiffer than glass fibres, however only standard modulus is stronger than glass fibres in tension. The higher modulus fibres are very brittle and are not suitable for general aeronautical use. Aluminium- lithium This is part of series 8000 of aluminium alloys. Having low density, the lithium reduces the weight of alloy while offering strength which is comparable to series 7000 (also a higher strength aluminium alloy made from zinc) and competes with composite materials. Aluminium lithium also has high specific modulus and excellent fatigue and cryogenic toughness properties. The disadvantages of aluminium lithium is reduces ductility and fracture toughness in short transverse direction also the need to cold work this alloy to obtain peak properties and accelerate fatigue crack extension rates when cracks are micro structural small. By using aluminium lithium in aircraft wings will enable low costs flying as it saves weight and fuel consumption costs, also this would lead to a reduction in maintenance costs. Fatigue affects materials after long term exposure to cyclic loading using aluminium lithium is stronger than carbon fibre therefore aluminium lithium can withstand fatigue longer. Aluminium lithium is currently being used on the Airbus A380, and under investigation with Boeing. Analysis Current material The current material used for aircraft wings is aluminium. This material is currently used to construct aircraft wings. This is because this material is light in weight, easy to machine, easy to shape also this form of aluminium is easy to machine in order to meet required standards such as high yield strength in ratio with the weight, and also aluminium 2024 also has very good fatigue resistance. However, this form of aluminium alloy has poor corrosion resistance therefore in order to protect against this the alloy is cladded with pure aluminium, this however has a downside to it as it further reduces the fatigue resistance of the alloy. The advantages of aluminium are: Light weight Easily shaped/cast/forge Good electrical conductor Good thermal conductor Easy to machine The disadvantages of aluminium are: Expensive to refine (must be done by electrolysis of fused salts) Poor chemical resistance (acids and base) Loses strengths when heated Cladded with 6.25mm of pure aluminium, if that is broken, the material begins to corrode fast. Alternative materials The alternative materials that can be used are: Titanium This metal has a high strength to weight ratio, a relative density of 4.5 which is 60% heavier than aluminium however it is twice as strong. Titanium has excellent corrosion resistance properties this is due to the oxide film which forms. Titanium is not normally susceptible to stress, fatigue, intergranular or galvanic corrosion, putting or localised attack.

Its high temperature properties are however disappointing.; the ultimate yield strength falls rapidly above 425 degrees Celsius and atmospheric oxygen and nitrogen absorbent above 540 degrees Celsius makes the metal brittle and worthless after a long term exposure. The ideal type of titanium to use on an aircraft wing would be the combined (C) class as it does meet to requirements for an aircraft wings. However, the major drawback for this material is when working with titanium extra care must be taken when making due to its extreme work hardening properties. The advantages of titanium are: Lightweight Strong Able to withstand high temperatures Corrosion resistant The disadvantages of titanium are: Expensive Process for forming and joining titanium are complex and expensive Glass Reinforced Fibres The fibreglass is used for reinforcement for thermosetting resins in aircraft applications is available as a cloth in many different weights and weaves as a loose of fibreglass.

The advantages of GRF are: Strength and resistance can be adjusted during the manufacturing Impact resistance Lightweight Heat resistant Will not corrode Able to withstand all but the strongest forms of acid and alkali The disadvantages of GRF are Easy to damage Expensive machines required to produce Requires special storage Although glass reinforced fibres are very good with respect to the advantages and disadvantages, it may not be the ideal choice to use as a material for an aircraft wing as it would be expensive to produce and store, and also there are many types of glass reinforced fibres but not a particular type could be chosen because there is not a material which is specifically ideal and has all the characteristics required for an aircraft wing. Aramid Aramid fibres have very high impact strength with the damage confined to small areas. Due to this, Aramid can be used in areas prone to stone and runaway debris damage, so this could be useful for use on aircraft wings. However, Aramid fibres have lower compression strength than carbon, it absorbs moisture more readily than glass or carbon, also Aramid deteriorates in strong sunlight. Aramid is more difficult to cut, drill or sand then either glass or carbon; it also does not give clean edges. The advantages of Aramid are: High tensile strength Impact resistant Ten times as strong as aluminium 400% stronger than GRF 20% stronger than carbon fibre The disadvantages of Aramid are: Low compressive strength then carbon Absorbs moisture more than glass or carbon fibre Deteriorates in sunlight Difficult To Cut, Drill or Sand Does not give clean cut edges Aramid is a very good material to use, however it is important that when making aircraft skin the wings must be smooth and easy to machine, due to Aramid not being able to provide these key features, it should be used for this part of the skin, however, Aramid should be considered for the leading edge of the aircraft wings, because it has the characteristics required to withstand stone and runaway debris damage. Aluminium- Lithium Having low density, the lithium reduces the weight of alloy while offering strength which is comparable to series 7000 (also a higher strength aluminium alloy made from zinc) and competes with composite materials. Aluminium lithium also has high specific modulus and excellent fatigue and cryogenic toughness properties. The disadvantages of aluminium lithium is reduces ductility and fracture toughness in short transverse direction also the need to cold work this s alloy to obtain peak properties and accelerate fatigue crack extension rates when cracks are micro structural small. Fatigue affects materials after long term exposure to cyclic loading using aluminium lithium is stronger than carbon fibre therefore aluminium lithium can withstand fatigue longer. The advantages of aluminium-lithium are: 10% denser than aluminium 2024 Lightweight 10 15% higher modulus than aluminium 2024 Excellent fatigue and cryogenic toughness properties Higher stiffness Superior fatigue crack growth resistance The disadvantages of aluminium-lithium are: Reduced ductility Low fracture toughness Aluminium- lithium is a new concept within the aviation industry which allows the industry to progress in a new direction, this allows an aircraft to be light, efficient yet have the same amount of or more power to transport both passengers and freight. Also, with aircraft being so light it may allow even bigger aircrafts then the currently produced Airbus A380, and Boeing 787 to be produced. Aluminium- lithium the characteristics required for use on aircraft wings and therefore should be considered for this project. Conclusion In conclusion aluminium- lithium should be used as it has the properties such as light weight and excellent fatigue and cryogenic toughness properties required for an aircraft wing and carry the weight loaded on to the plane hence enabling aircrafts to be designed on a bigger scale in order to carry more cargo and passengers as is proven by the production of the Airbus A380 which is one the largest planes in production giving a higher power to weight ratio. The A380s wing is sized for a maximum take-off weight (MTOW) over 560 tonnes in order to accommodate these future versions, albeit with some strengthening required. The stronger wing (and structure) will be used on the A380-800F freighter. This common design approach sacrifices some fuel efficiency on the A380-800 passenger model, but Airbus estimates that the size of the aircraft, coupled with the advances in technology will provide lower operating costs per passenger than the 747-400 and older 747 variants.  [6]   Reference Books Used; British Airways Engineering Training Part 66 Module 6- Materials and Hardware.

Anglo Saxon Literature :: History Beowulf

Anglo Saxon Literature W Y R D The word wyrd generally means fate in Anglo Saxon literature. It is one of the recurrent themes in many old English works. For example, wyrd is seen as the force that determines the result of events in Beowulf. In another story, â€Å"The Wanderer,† wyrd is mentioned several times. In the first few lines, the speaker states that â€Å"fully-fixed is his fate† (Norton 100). This shows that wyrd is unchangeable. Then, he goes on to say â€Å"Words of a weary heart may not withstand fate† (Norton 100). Here it seems that a person must be strong, brave, and show no emotion in order to be able to cope with wyrd. Later on, wyrd is proclaimed as â€Å"mighty† because not even earls are able to escape their deaths. Lastly, we see the power of wyrd: â€Å"The world beneath the skies is changed by the work of the fates† (Norton 102). This quote reflects the belief of Anglo-Saxons that wyrd is an invisible, powerful force that controls the outcome of a personà ¢â‚¬â„¢s life. This final use of wyrd may also refer to the â€Å"Weird Sisters.† They are seen in Shakespeare’s play Macbeth. The Fates are also an important part of Greek culture. Usually they are depicted as three horrid old ladies who share one eye with which they see the future. They also are seen tending to so-called â€Å"threads of life.† Each time they cut a thread another soul goes to the underworld. This portrayal of the Fates can also be related to the â€Å"Measurer† in â€Å"Caedmon’s Hymn.† The â€Å"Measurer† seems to be the one who decides the destiny of a person, just as the Fates: â€Å"The Measurer’s might and his mind-plans† (Norton 24). Like witches, the Fates are sometimes shown surrounding a large pot, brewing spells. Women were given the opportunity to pick their own husbands. The families acted merely as financial advisors. However, in many circumstances, women were married off to members of enemy tribes in order to bring peace. Hence, they were given the name peace-weavers. Women, depending upon social standing, were also educated and wise, sometimes acting as advocates and protectors of the people of the village. Over all, the women in Anglo Saxon were well respected and valued. Scene Analysis: Beowulf Fights Grendel's Mother Summary In the Howe translation of Beowulf, the scene depicted on pg. 26-29 deals with the battle between Beowulf and Grendel’s mother.

Exploratory Paper

Exploratory Paper-Revise English 1302/July 4th On-line Class 20 July 2011 Unhealthy Food Banning From Schools Presently, children in Los Angeles Schools are being denied chocolate milk due to an unhealthy food ban. According to an L. A. Times article, chocolate milk being served in Los Angeles public schools has as much sugar as a cup of regular Coke (Macvean, par. 9). Such findings have resulted in chocolate milk, which accounts for more than half of the milk consumed in Los Angeles public schools, being banned on July 1, 2011.So, why are Los Angeles Schools and other schools in the nation enforcing unhealthy food bans? It is not surprising that Los Angeles and many school districts in the country have been introducing strict bans on unhealthy foods due to an alarming problem with childhood obesity. The problem became more apparent when a national study conducted by the Federal Drug Administration (FDA) found that one in three American children attending public schools were reported to be obese (Chase, par. 7).Most of the blame for the alarming ratio of student obesity was directed to â€Å"Junk† foods and sedentary activity. In response, Los Angeles schools and many other schools in the country have made it a mission to offer their students ealthier menus and encourage good eating habits largely by banning food items that are deemed unhealthy. The crusade to ban unhealthy foods from schools has had its fair share of critics, primarily by the producers of the labeled snack and soda foods who argue that banning their products will not solve the obesity problem that is currently affecting children.They claimed it is not there product, but the lack of exercise is the cause of obesity. In response to the obesity issue, producers such as Pepsi-Cola have generously provided large monitory donations to school physical education programs. School administrators and student organizations themselves have argued that food bans on snacks and sodas would create a fin ancial burden for schools, and is the wrong way to target children eating habits.One major concern is that unhealthy food bans in schools will harm school fundraising efforts for sports programs and school bands that have relied on extra revenue from sodas and candy sales. According to an article in Education Week by Linda Jacobson, 30 percent of California high schools that generated income from such products each raised more than $125,000 a year (23). Korey Capozza of Prevention magazine reported that the average teenager consumes almost two cans of soda per day that are usually purchased from a school vending machine (par. 1).An average two soda consumptions could generate thousands, or even millions of dollars in soda-company incentives to a school district's budget. A popular protester of such policies that ban unhealthy food is political conservative icon Sarah Palin. While visiting a private school in Pennsylvania she made a clear point about where she stood on the matter are losing their rights for an occasional classroom treat†like her cookies. Her focus was to push for laissez-faire, which would prohibit any government controls on what children can and cannot eat at school.Palin argued that government control on school foods is an assault on the American way of life, â€Å"On freedom and simple pleasures. On wholesome childhood delights and†¦ the integrity of the family' Oudith, par. 2). Despite debate, the popular trend by local governments in dealing with childhood obesity continues to be the banning of unhealthy foods in schools under the idea that this will encourage schools to provide nutritional meals and teach hildren how to become healthy eaters.To some degree, states like New York and California have a zero tolerance policy on unhealthy foods that can be sold or consumed on school premises. Both states also have extreme foods policies, which prohibit bake sales, treats given by teachers, and birthday cakes in the classrooms (Brow n, par. 2). A public school in Chicago has even banned the lunches students bring from home unless they have a medical excuse ensuring they will only eat the food provided by the school cafeteria (Eng, par. 5). According to an article in CQResearcher, many studies have found that eating habits start at a young age and the author of the article, Alan Greenblatt, believes that because of this, schools can play an important role in combating obesity (73). Greenblatt added that food controls is not the only solution and cautions that children will more or less fill up on unhealthy food outside the school (75). He also purposed that unhealthy school food bans should also include an increase in physical exercise and education about eating healthy that will also involve the students' parents to encourage them to prepare ealthy foods at home (Greenblatt 78).The federal government has also lent its attention on the problem of childhood obesity and has supported state government efforts to ba n unhealthy foods from schools so much so that in July of 2011, President Barrack Obama signed the child nutrition bill which places a national ban on selling candy, sugary soda, salty and fatty food in school snack bars, vending machines, and a la carte cafeteria lines (Severston, par. 1). This measure by the federal government has emphasized the argument that unhealthy food bans in schools are too intrusive nd even go against American values.The only clear conclusion in the debates involving child obesity is that something has to be done by somebody. Why not start teaching children to eat well in a place where they do most of their learning? For the fact schools are where children spend most of their time, and makes logical sense to lay the foundation for healthy habits there. It is also uncertain whether unhealthy foods on the long run will create financial difficulties for the schools or force student to eat those banned items outside of school.Nevertheless, schools can probably enerate extra revenues sales if vending machines are refitted with healthier alternatives, such as granola bars and water. This will also motivate the producers of â€Å"Junk foods† to provide and advertise healthier products to children. Hopefully a healthy eating trend among children and adolescents can start with no â€Å"Junk† food venting machines. As far as â€Å"laissez-faire† is concerned, I have no objection to the government showing concern about what our children eat in our schools and taking on the obesity problem head-on to help improve the quality of life in our society.

Gone in 60 Seconds essays

Gone in 60 Seconds essays Gone in 60 Seconds reunites actor Nicolas Cage with producer Jerry Bruckheimer. The two are known for some of the best action movies ever, including The Rock and Con Air. Gone in 60 Seconds carries on that very same tradition with fast high speed action and fast high speed car chases. Gone in 60 Seconds tells the story of Randall Memphis Raines (Cage), a retired car thief who has given up the life of crime and has settled down. His younger brother (Ribisi), is still very much into the car stealing scene, and has gotten himself into trouble with his boss by botching a high priced boost. The boss then sends an ultimatum to Memphis: either he comes back to the business and lifts 50 cars in 4 days, or his brother dies. Memphis decides to return to his former profession for the sake of his brother, and gathers some old friends and forms a crew of car boosting experts. The chemistry between most of the characters works. Cage plays the protective older brother to Ribisi, a kid whos gotten into the life too deep and finds himself in more trouble than he can handle. Robert Duvall is the veteran who masterminds the whole The supporting cast is there for some comic relief. They fill the movie with many cliches and stereotypes. Ribisis young friends are the exact opposite of Cages crew. They are using their new high tech gadgets to steal cars for the money, unlike Cage and his crew who do it for the rush. In one of the funnier scenes, a member of Cages team is car-jacked while he is driving away with a stolen car. Instead of surrendering, he curses, gets out of his car, beats down the car-jacker, and lectures him that hes an amateur who doesnt know the first thing about reall ...

The Importance of Life - Our Town.

The Importance of Life - Our Town. There are many phrases that are used today to reference the shortage of time or the importance of life. Carpe diem (seize the day), which is a Latin phrase that has become part of the English language urges people to live for the moment. But no matter how often individuals hear these phrases, they seldom listen. Mankind likes to believe that we control our fate. We position ourselves in what we believe are the most optimal places in our lives. Time on Earth is a gift and an irreplaceable resource that is ours to use as we see fit. The hustle and bustle of everyday life makes us blind of its true value. The play Our Town by Thornton Wilder makes reference to these points as the main theme of the play. When Emily Webb asks the Stage manager, "Do any human beings ever realize life while they live it, every, every minute (Wilder)?" The play forces you to reference all of the times that things were too busy, and you did not stop to enjoy the little things in life.English: Photograph of Am erican author Thornton Wi...Throughout the play there are many examples of characters not realizing the importance of life. Our Town is a prime example of how American playwrights used expressionism and symbolism to try to change people's perceptions of life (Haberman 2-3). The main theme of Our Town is that people should appreciate life while they are living it. The author allows the audience to see that ordinary uneventful activities are important.Our Town is presented in three acts. Each act sends a different message. Act one, "Daily Life," shows what the town looks like. This act gives information from the past, lays out the town's structure, and sets up significant events in the town. As this act is played out, the...

Che guevara Movie Review Example | Topics and Well Written Essays - 250 words

Che guevara - Movie Review Example He only relates to what his eyes seen as clearly depicted by his reactions to their host, the wife to Aberto friend at Necochea. The scene therefore becomes quite clear that this is a duo, embarking on an adventurous trip at the expense of their academics. The movie depicts the two (Ernesto and friend) as trickery and rebellious through the way they defraud people of shelter, transport and food. The unfolding of the film however depicts the two in fun and adventure unlike through whatever the narration actually portrays of the duo; stowaways, bandits and hooligans. The events of the film reveal gradual change of Guevara through the garment of civilization and the ties of cultural norms. The movie clearly depicts the ‘needy’ aspect throughout their adventures and which ultimately served to transform their character. Their encounters and diary depicts their perception of social injustices as well as inequality as people struggle in poverty while others enjoy affluence. It also depicts some change through the live of Guevara who stands to see through hope; future dreams in starting up a hospital to help the poverty stricken community. A revolutionary episode set in through the intention of the two to setting up revolutionary movements to empower poor people against exploitation by those in power. The movie then sets a close at the airport where in acknowledgement of the change that had happened within them over the trip, the duo parts ways (Carte
