History Of Brakes And Principles Of Hydraulics Engineering Essay

History Of Brakes And Principles Of Hydraulics Engineering Essay Landing gears are one of the most important parts of the aircraft and play an important role because it can make the aircraft run through runways and lands the aircraft to safety with the aid of the braking system and other systems. The modern brake system has been refined for over 100 years and has become extremely dependable and efficient. The whole draft talks about the hydraulic brake system. Modern braking systems are complicated and understanding the operation of a braking system requires specialized skills and training. Brakes are the most important feature of any modern transportation these days. The principles of brakes in a landing gear of the aircraft gave us the idea that making a simple hydraulic break system would be our main project. The content is designed to show the insight of the principles of operation of the hydraulic break, components and its functions. The advantages and disadvantages against different types of brakes and other terminology. :History oF Brakes: All cars need a brake system; therefore it has been present in the automobile since its invention. However, the technology of the components and the design of the brake system have evolved throughout the years. In the early days of the automobile, drum brakes were the standard. Drum brakes offered several advantages over other types of brakes. One of these was that the drum could keep out water and dust, materials that could damage disc brakes which were out in the open. The other, more important advantage was that drum brakes required drivers to apply less pressure on the pedal as compared to disc brakes. This was especially important in the days before hydraulic and power brake systems, both of which decreased the amount of pedal pressure needed. The next major advancement in brake technology came in 1918 with the invention of four-wheel hydraulic brake systems by Malcolm Loughead. It is interesting to note that Loughead was a member of the Lockheed family, a company known better for producing airplanes. The hydraulic brake system replaced the mechanical brake system that was in use at this time. The mechanical system had numerous disadvantages. It made it difficult to brake all the wheels evenly, often causing a loss of control. In addition, it required drivers to exert tremendous amounts of force on the brake pedal to slow the car. The hydraulic brake system multiplied the force that was applied to the brake, lessening the amount of force needed to be applied to the brake pedal by the driver. This system was first used in the 1918 Duesenberg. Its advantages quickly caught on and by 1929, four wheel hydraulic braking systems were standard equipment on most higher priced cars. It took a few more years for the feature to becom e common on lower price cars. As the speed of automobiles and their weight increased, better braking systems were required. The main problem with drum brakes is that the heat is not efficiently disbursed. The heat that is produced inside the drum does not escape easily since the drum prevents wind from drawing it away. However, disc brakes were open to the passing wind. This allowed the heat to be carried away which increased the efficiency of the brake. It is interesting to note that disc brakes were first used in 1902. However, their use was limited up until the 1950s since their efficiency was not required and they required more pedal pressure to operate. The reason for the higher pedal pressure is that disc brakes have no self-servo effect or no self-energizing capacity that the drum brakes have. The self-servo effect is caused by the forward motion of the car. This forward motion helps pull the brake shoe into contact with the drum. This helped lower the required pedal pressure. Now that their efficiency was needed and the hydraulic brake system multiplied the force applied to the brake pedal, disc brakes seemed to be the better alternative. Chrysler was the first to widely introduce the disc brake in its cars in the early 1950s. The system did not have much success. It seemed that the brake pressure required of the driver was still a little to great for the system to gain widespread consumer acceptance and therefore it was dropped. It finally took the failing automaker Studebaker to reintroduce the system in 1964. This time it saw much more success and in a few years, disc brakes were common on most new cars. One of the reasons that disc brakes were a success with the Studebaker and not the Chrysler was due to the development of the power braking system. Power brakes became common in the 1950s, after Chrysler had developed and dropped its disc brake program. The system assisted the movement of the piston in the master cylinder which meant that the driver needed to apply less peddle pressure to get the same braking effectiveness. Therefore, since ease of braking was no longer an issue, the adoption of the more efficient disc brake became widespread. Another development in braking systems came with anti-lock or anti-skid braking. With conventional braking systems, when the brakes are applied with enough pressure, the wheels will lock up. This results in a loss of steering effectiveness which may cause a loss of control. With anti-lock braking, the wheels do not lock up, allowing the driver to continue steering. Anti-lock brakes are not a new technology. They had been used in large aircraft since the 1950s and the British had used them in race cars in the 1960s. The first automaker to use this technology in its cars was Ford in 1969. It placed anti-lock brakes in the luxury Thunderbird and Continental Mark III. Today, anti-lock brakes are common on many new cars. : Basic Principles of Hydraulics: What is pressure? Pressure can be defined as the force per unit area and is expressed in Newtons per square millimeter (N/mm ²) or in bars and pounds per square inch (lbs/in ²) or p.s.i. in U.S. pressure. Formula: P = F / A Where: P = Pressure; F = Force; A = Area What is hydraulics? Liquids or fluids which are under pressure are usually used to transmit power through pipelines. The fluid power is converted into mechanical power by using rotary or linear actuators. What is Pascals Law? Pascals Law comprises a set of principles formulated in 1648 and states that pressure applied to a confined fluid at any point is transmitted undiminished throughout the fluid in all directions and acts upon every part f the confining vessel at right angles to its interior surfaces and equally upon equal areas. It defines the fundamental principle of power transmission by a hydraulic system. Figure 2: Pascals Law Pressure is created only when: The system is closed There is no air trapped in the system An attempt is made to compress the fluid Another important relationship in hydraulics is the area of the piston, the distance it moves, and the volume of fluid displaced. Formula: Volume =Area * Distance Fluid Compressibility: All liquids have a very high resistance to compression while air has a very low resistance to compression. Liquids used in hydraulic systems are also known as hydraulic fluids. Figure 3: Hydraulic fluid Bramahs Press: States that under a given load, the smaller the area it acts upon the greater the pressure produced and the greater the area under pressure, the greater the force available. Pressure = Load / Area Figure 4: Bramahs Press In an aircraft hydraulic system, Bramahs principle can be applied to the movement of different loads using actuators subject to one pressure. The figure above shows a large load and a small load being pushed by actuators having different piston areas. Bernoullis Principle : The relationship between the velocity and pressure exerted by a moving liquid is described by the Bernoullis principle: as the velocity of a fluid increases, the pressure exerted by that fluid decreases and as fluid decreases, pressure is increased. Figure 5: Bernoullis Principle Figure 6: Bernoullis principle also allows wings to produce lift Hydraulic Fluids: Hydraulic system fluid or liquids are used to transmit and to distribute the fluid to various units to be actuated. They are able to do this because they are almost compressible. If a number of passages exist in a system, pressure can be distributed to all of system by means of the liquid. Manufacturers of hydraulic devices usually specify the type of liquid best suited for use with their equipment, during working conditions, the service required, temperatures expected inside and outside the systems, pressures the liquid may withstand, the possibilities of corrosion, and other conditions. Figure 7: Types of hydraulic fluid Figure 8: Hydraulic Fluid (Aeroshell brand) Properties of Fluid: Fluids are incompressible They have a reasonable density with very little variation changes in temperature. Low rate of change of viscosity with temperature changes Large working range of temperature (-80 °C to +70 °C) Good Lubricating Properties It isnt harmful when in in contact (skin, hands) It doesnt foam Chemically stable with changes in temperature Good storage life Doesnt attack nor damage rubber. Fluid is preferably non-flammable Efficiency: Friction between the fluid and the walls of the pipes depends upon: The velocity of the fluid of the pipelines The bore, length and internal finish of the pipelines The number of bends in the pipelines and the radii of the bends The viscosity of the fluid What is Viscosity? It is one of the properties of hydraulic fluid. Viscosity is internal resistance to flow. Viscosity increases with a decrease in temperature. The knowledge of viscosity is needed for proper design of required temperatures for storage, pumping or injection of fluids. There are two related measures of fluid viscosity known as dynamic (or absolute) and kinematic viscosity. Types of Hydraulic Fluid: 1 Vegetable Based: (MIL-H-7644) is composed of a caster oil and alcohol. It is dyed blue. They are mostly used in older type aircraft. Natural rubber seal are used with vegetable base hydraulic fluid. This type is flammable. And the system may be cleaned with the use of alcohol. Figure 9: Vegetable based fluid 2 Mineral Base: (MIL-H-5606) it is processed from petroleum. It has an odour similar to penetrating oil and is dyed red. Synthetic rubber seals are used with petroleum base fluids. This type of fluid is flammable. They are used in common aircrafts and the precaution is damaging to rubber tyres. Figure 10: Mineral base fluid 3 Synthetic Base: (MIL-H-8446) This is one of the most commonly used fluid of this type. This fluid is of a clear purple colour or either dyed green. They are fire resistant. The seal material used is synthetic butyl Teflon and the precaution is of damaging to surface finishes. Figure 11: Synthetic base fluid These three types of fluids cannot be mixed nor any of them are compatible with each other.

Coffee Industry in the UK Essay -- Business Marketing Essays

Coffee Industry in the UK The coffee industry has grown rapidly since the 1990s; before Starbucks emerged, people were used to drinking low quality coffee from tins. Starbucks introduced fresh coffee made from top quality beans that have excellent taste and drinks such as the caffe latte and cappuccino, which have helped to fuel the development of the coffee market into a multi million pound industry. The size of UK branded coffee chains have quadrupled from 1999 to 2004, with a current market turnover of over  £1 billion. 2 Market Forecasts The coffee market is forecast for continued growth and expansion, without threat of saturation in the near future. In 2004 the coffee market was estimated at having around 2,299 outlet units and it 2006 it is predicted that the number of units will have increased to an estimated 2,965, with the growth of the branded coffee sector predicted to increase by 11% between 2004 and 2006. Indeed, branded chain outlets have accounted for most of the coffee market growth according to forecasts by industry analysts Allegra Strategies. Allegra claims that although there are more independents than branded coffee chains, in 2005 and 2006 it is expected that more branded than independent chains will be opening. Indeed, some independents. such as Bewley’s in London, have had to close down. 3 Macro - environment analysis of the market Social The coffee market must adapt to a change in consumer attitudes or else it may be threatened by health and lifestyle issues. In 2003 the hot drinks market declined by an estimated 2.3%. Consumers, especially young people, are becoming more health conscious which makes coffee a less attractive choice; the increasing number of alternatives available such as health and energy drinks are becoming competitors in the coffee industry. Research carried out by Mintel shows that there is an increased diversification of tea, with a trend towards premium and herbal teas. The coffee industry are responded to this change in attitude by provision of de-caf drinks, options such as soy milk, and alternative drinks such as freshly squeezed fruit juices, chai lattes and herbal teas. People are now working harder than ever before but have more leisure time; they now use coffee shops to socialise.

They create litter-Aside from polluting beaches and waterways, plastic bags for example in China plastic bags are blowing around streets of China, they are so common they've earned the name â€Å"white pollution.† It is not environmentally friendly and may cause harm to children and water life all around the world. It should also be banned for a list of reasons such as it is unfriendly to the environment and may be harmful to children and water life all around the world and also it takes years for plastic bags to break down and we're not even able to recycle them. No, because plastic doesn't break as easily as glass and is water-proof. They take a long time to biodegrade-Most plastic bags used either end up as litter or in landfills. Plastic bags pose a suffocation hazard to people, particularly children, and pets. Plastic bags are made out of non-biodegradable substances. They are durable they do not rot. Making plastic bags can lead to exhaustion of oil, because to make a lot of plastic bags, we need a lot of oil. If we reduce oil we could save much more oil. Plastic bags even kill a lot of marine animals. Plastic bags gets blown into the ocean and floats around like a jelly-fish. A lot of sea-creatures choke and die for mistaking them as their food.

The Mozart Effect Essay - 931 Words

It has long been believed that music can evoke specific thoughts and feelings from the listener. But can music –specifically the music of Wolfgang Amadeus Mozart- summon hidden intelligences within the human brain? That is the question scientists are trying to answer. In the mid-nineties, scientists, Frances Rauscher, Gordon Shaw and Katherine Ky, claimed that music could boost the listener’s intelligence up to 9 points (Steele 2). To many, this allegation seemed a bit far-fetched and soon other researchers began recreating the Rauscher, Shaw, and Ky experiment in hopes of discrediting their findings.

The results of the experiment were not much different than the results of the Rauscher, Shaw, and Ky experiment. This conclusion was groundbreaking in the science world because it completely discredited the claims that music has the ability to change the way a person thinks and potentially make them smarter. After the original experiment was published, marketers took advantage of the profitability of the claims. They distributed cassettes, books, and CD’s across the globe with guarantees that if parents expose their infants to the right kind of music, it â€Å"would speed intellectual development† (Steele 3). Their promises and claims were successful and Baby Mozart CD’s are still being played through headphones around the big bellies of pregnant women.

American Rock N Roll Essay - 1578 Words

American Rock ’n’ Roll was a huge influence on the idea of Pop as it affected young people and gave them their own distinct interests. Pop figures at the time such as Elvis Presley and the Beatles gripped the youth of the mid-20th century and defined a discernible difference between the young and the old. Post-war depression was replaced by a youthful optimistic spirit, which allowed for expression of self among the youth of American society. The optimistic spirit offered by pop culture icons allowed the youth to recover from a society which condemned them. An extreme example of this condemnation is the Kent state massacre of 1970 where 4 students were killed and 9 were wounded (History.com Staff 2009). Fashion, particularly the mini skirt, was the largest expression of Pop. The mini skirt displayed multiple Pop styles through the change of its shape while also being visually influenced by art styles coming into existence at the time such as Pop art and art deco. Pop wa s also influencing art/design and architecture/furniture styles. These styles are evidenced through bold designs that included bright colours, patterns, and unusual shapes but overall were exciting and eye-catching. They gave people incentive to keep up with current styles while still maintaining appeal to the young people. Both during and after this period of pop and consumerist development, a change in designoccurred.

Happiness Essay Example For Students

Happiness Essay HappinessHappiness: In one word, this concept exemplifies the American dream. People go to any means by which to obtain the many varied materials and issuesthat induce pleasures in each individual, and intrinsically, this emotionremains the ultimate goal, John Stuart Mill, a nineteenth century philosopher,correctly advocated the pursuit of happiness, and maintained the concept thatabove all other values, pleasure existed as the final destination, Millshedonistic views correctly and rationally identified a natural human tendency,and his Utilitarian arguments strongly support the theory that above all else,happiness is the most important dream to be fulfilled. Upon researching forthis paper, I came across a counter argument, which was based on metaphysics. Immanuel Kant, in Groundwork of the Metaphysics of Morals, defends his strongbeliefs in the issue of a good will, and surfaces as MMs chief opponent on thetopic of metaphysics, The issue diminishes to a clash between emotions andpleasures ve rses rationality and logic. Yet, what use is logic when the goodagent is miserable? Mills stance within Utilitarianism exists as the morefavorable of the two beliefs, for happiness exist as the one intrinsicallyfavorable element, not an emotionless mind. The main defender of the Utilitarian system exists within the Greatesthappiness Principle. Mill lived as a chief advocate of this concept, whichsupports the idea that a decision is morally correct as long as it increases andencourages pleasures and happiness. Kant, however, in his endless quest toremain separate from emotions and thrive only on logic, would argue thatautonomy should be placed above happiness in a list of intrinsic values. A goodwill, however, does not comfort an individual in any way if happiness does notaccompany this asset, Consider this example of a seemingly happily marriedcouple. The wife in this duo is madly in love with her husband fiercely loyal,and completely happy with her marriage and children. The husband, however, aswrongfully strayed, and had a brief, but damaging affair behind his wifes back. Kant would argue that autonomy reigns over pleasure, and the woman shouldtherefore want to be informed of her husbands adultery, Mill would greatlydisagree. By revealing the secret of the past affair, the womans happy worldwould be instantly shattered. Her pride would diminish, her stability wouldfall apart, and the children especially would be forced to view a nasty side oftheir beloved father. In this case, individual control is greatly overshadowedby the need for happiness. The husband is no longer acting unfaithful and thefamily can easily continue to live in a happy realm, If the secret were tobecome uncovered, all members of this circumstance unavoidably would becometerribly disappointed, Under the Greatest Happiness Principle, the wife shouldnot be informed. Since happiness truly lives as the ultimate in human desires,sparing such immense amounts of pain truly is the logical choice, Millsargument prevails, and all those involved remain happy. Through this example,one can easil y see that although autonomy is often a favorable feature, it doesnot overshadow the importance of happiness. One of the main arguments against Utilitarianism exist in the lack ofapparent fairness. An advocate of the Kantian logic principle would argue thatMills belief system does not allow for equal treatment, When considering whatis best for an entire society, however, it is necessary for certain individualsto endure suffering. The good of society remains the ultimate goal, andunfortunate pain is therefore inevitable, If young children are being killed ina certain community, the obvious good for this society is discovering andpunishing the murderer. Especially when children are involved, peopleautomatically demand prompt justice. The officials of this area have searchedimmensely for the accused, yet no leads have surfaced, and the communitysuddenly erupts with anger, they demand that someone be punished, As aUtilitarian, the police chief sees a window of opportunity. A drug dealer hasrecently been brought in on yet another drug selling offense, and the chiefdecides to coerce the invalu abl e member of society into confessing the crime athand, By doing so, the community instantly reunites in support and a dangerousand deadly revolt is avoided, and a menace to society is right back where hewould have been regardless of his confession: behind bars, Kant, however, wouldargue that logically, the chase for the true offender should continue. He wouldshun the emotional decision to make the whole society happy by ignoring therational decisions. But since the community obviously chooses happiness overlogic, Kants arguments are irrelevant. In addition, Kant believes in adecision making process completely separate from the natural human emotions,Such a demand is possible only for a character such as Star Treks Dr. Spock,for human emotions are as much a part of every day life as the decision makingprocess itself. Logically speaking, therefore, Mills Utilitarianism argumentsmaintain the largest dose of validity. .ufab5a64e46b910581aede84a3640893e , .ufab5a64e46b910581aede84a3640893e .postImageUrl , .ufab5a64e46b910581aede84a3640893e .centered-text-area { min-height: 80px; position: relative; } .ufab5a64e46b910581aede84a3640893e , .ufab5a64e46b910581aede84a3640893e:hover , .ufab5a64e46b910581aede84a3640893e:visited , .ufab5a64e46b910581aede84a3640893e:active { border:0!important; } .ufab5a64e46b910581aede84a3640893e .clearfix:after { content: ""; display: table; clear: both; } .ufab5a64e46b910581aede84a3640893e { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ufab5a64e46b910581aede84a3640893e:active , .ufab5a64e46b910581aede84a3640893e:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ufab5a64e46b910581aede84a3640893e .centered-text-area { width: 100%; position: relative ; } .ufab5a64e46b910581aede84a3640893e .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ufab5a64e46b910581aede84a3640893e .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ufab5a64e46b910581aede84a3640893e .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ufab5a64e46b910581aede84a3640893e:hover .ctaButton { background-color: #34495E!important; } .ufab5a64e46b910581aede84a3640893e .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ufab5a64e46b910581aede84a3640893e .ufab5a64e46b910581aede84a3640893e-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ufab5a64e46b910581aede84a3640893e:after { content: ""; display: block; clear: both; } READ: Eliezer Wiesels Night EssayOther opponents to the philosophical viewpoint of Utilitarianism statethat followers of this belief system often promote an ignorant lifestyle, Theymaintain that advocates of the Greatest Happiness Principle believe in thetheory that ignorance is bliss, Again, such reasoning is quite faulty. Displaying the erroneousness of this statement can be done by examining theissue of AIDS, An opponent of Utilitarianism would say an Infected HIV victimwould not want to be aware of his disorder, Such a belief is extremely incorrect. Mill and other Utilitarian are strong advocates of education, for withintelligence, greater levels of achievement and happiness can be obtained. Amember of this belief system would rightly argue that being aware of thedisorder could increase long-term happiness, for treatments and support fromfriends and family could greatly aid the victims fight against his or heralhnents, Mills therefore strongly support education systems and believe inmaking society as a whole as happy as possible. In the case of the AIDS victim,a Utilitarian would also support the notification of the disorder to the victimin order to spare others of contracting the virus, The happiness of the majoritywould not be increased by an unknowing HIV carrier spreading the disease toother defenseless individuals, Utilitarianism clearly is not a ignorant way tolive, and the Kantian philosophy of ignoring the irrational system of emotionscannot refute this standard. Without happiness, the other opportunities and necessities lose nearlyall levels of importance. A true Utilitarian supports only those concepts thatpromote the highest levels of pleasures, and as Mill states, encourages onlythose actions that promote real happiness, From a Kantian viewpoint, rationalityand the possession of a good will remains the most important element, but evensomeone with the truest and most logical of intentions can easily exist in arealm of pure depression. The one link that exists between these oppositebelief systems is the concept that, all decisions should be made outside ofones personality. The key is that Kant said this decisions should be madewithout any regard for human emotions, A request of this magnitude is a part ofa utopian society only, for ignoring ones emotions is an illogical assumptionin itself, If your child and wife are both dying, deciding which one to savecannot be made without some emotional influence, Utilitarianism allows for theemotional side of life but requests only that the Greatest Happiness Principlebe strictly followed. Any truly decent human being naturally follows such arequest every day, Decisions are made based on the greatest level of happiness,That way, the largest majority of people benefit, and the greatest amount ofhappiness is achieved. Yet as Kant believed, a more morally correct decisionlies at the heart of every dilemma. How does one decide who is morally more correct to save in an instancewhere two cherished loved ones are passing away, and only one individual may besaved? And even more importantly, how does one do so without regard emotions?I personally feel that living strictly by the doctrine of Kantian philosophy iscompletely impossible. Being a Utilitarian and hedonist, such as Mill, makesmore sense to me.
