Why do people want to develop technology? This questions has a lot of answer but I think people want to ease in own life. Today, our lives are very comfortable thanks to technology. Sometimes this is dangerous for human’s life. Maybe they can gain weight. Because people don’t make sport but they want to speed with another vehicle. From past to present, researchers (mechanical engineers, electrical engineers) use to a machine for motion. They're trying to develop every time .This machine is Engine. Engine is very important for every machine and every Engineer. Engine is very complicated machine. People need to use some energy. Actually people need to convert energy in engine for motion. We usually use fuel for energy. Engine is burn fuel and ıt creates heat and motion. It creates heat because ıt creates friction so friction always obstructs motion in engine. In the word, many kinds of engine are produced by people. Some of these are reciprocating-engine are electric motor. Generally, we use reciprocating-engine. For example: Cars, trains, aircraft. We have two kind of reciprocating-engine. First is internal combustion engines, second is external combustion engines. I will explain this engine types in other page. If you want to go anywhere quickly, we use any of these vehicles because time is very important for people. Formerly, people don’t have engine so firstly, I explain the story of engine Story of engine In a past time, people don’t have engine system so they use human’s power, wind or water power, animal power. When the number of people increases, people want to easy life. And the engine was developed by people. Some researcher effects engine design. I research some researcher in internet. ... ... middle of paper ... ...outube.com/watch?v=DaF_K1R6PoI Ground Author (2013, December 24) “water pump” at Wikipedia URL: http://en.wikipedia.org/wiki/Pump Ground Author (2013, September 16) “spark plug (Turkish language” at Wikipedia URL: http://tr.wikipedia.org/wiki/Buji Ground Author (2013, December 30) “spark plug” at Wikipedia URL: http://en.wikipedia.org/wiki/Spark_plug Alican Gürcan (2013, April 16) “turbo” URL: http://www.forumotomobil.com/forum/otomobil-sozlugu/turbo-nedir-ne-ise-yarar-nasil-baglanir-ve-dikkat-edilmesi-gerekenler-nelerdir/ Ground Author (2013, December 19) “fuel injection” at Wikipedia URL: http://en.wikipedia.org/wiki/Fuel_injection Ground Author (2013, august 1) “Crankshaft” at Wikipedia URL: http://tr.wikipedia.org/wiki/Krank_mili Author (2010, June 28) “How the work car engine” URL: http://www.forumalev.net/teknik-bilgiler/420630-araba-motoru-nasil-calisir.html
After the steam engine was created in the early 17th century, many people and companies tried to take that same technology and apply it to automobiles. Nobody was successful until a British inventor by the name of Richard Trevithick created a multi passenger automobile that ran on a power source that was driven by a steam-propelled piston at high pressure (Bellis). Up until the mid 1900’s cars were only produced by specifically skilled blacksmiths, and were very expensive. There were only about 4,000 cars produced from the 1890’s to mid 1900’s (Bellis).
Automobiles have drastically evolved since they first came out in the 1880s.Automobiles have vastly changed since the 1880s to the 1920s. Henry Ford and Karl Benz played an enormous role into the making of the present day automobile. During the 1880s, automobiles used and engine called the internal combustion engine, and in the 1920s, automobiles used the external combustion engine. Lastly, during the 1880s to the 1920s, there were different model types of automobiles that were invented during that time. From the 1880s to the 1920s, automobiles became faster and more sturdy because the work of Karl Benz and Henry Ford, resulting in the present day automobile.
Starting in the late 1700's, European engineers began tinkering with motor powered vehicles. Steam, combustion, and electrical motors had all been attempted by the mid 1800's. By the 1900's, it was uncertain which type of engine would power the automobile. At first, the electric car was the most popular, but at the time a battery did not exist that would allow a car to move with much speed or over a long distance. Even though some of the earlier speed records were set by electric cars, they did not stay in production past the first decade of the 20th century. The steam-driven automobile lasted into 1920's. However, the price on steam powered engines, either to build or maintain was incomparable to the gas powered engines. Not only was the price a problem, but the risk of a boiler explosion also kept the steam engine from becoming popular. The combustion engine continually beat out the competition, and the early American automobile pioneers like Ransom E. Olds and Henry Ford built reliable combustion engines, rejecting the ideas of steam or electrical power from the start.
Since the development of the steam engine people had been interested in creating self-powered vehicles, this manifested during the industrial revolution as the train. However, as time went on people became interested in creating a vehicle that wasn’t confined to tracks. The earliest attempts were moderately successful but served little practical purpose. Automobiles first began to truly spread with the invention of the electric motor which created cheaper, more powerful, and safer automobiles. Still the automobile still had numerous problems and were mainly in the hands of the rich. It was the development of the internal combustion engine and the assembly line that was truly able to create a practical vehicle that could be used by all and propelled the automobile into the heart of American culture and made it one of the most significant inventions of the post-industrial revolution era, resulting in a complete revolution of society.
The Industrial revolution took place during the 18th and 19th centuries. It was a time when America switched from a rural society into an urban society. This was a drastic change in many peoples lifestyle. People moved from their farm homelands into cities. The reason for this was because there were many more job opportunities and availability for a better life. Many new inventions were discovered during the Industrial Revolution but it was a dangerous and harmful time with extremely bad working conditions, especially for women and children but helped improve the way the world is today.
Starting in the late 1700’s, European engineers began messing with motor powered vehicles. By the mid 1800’s, steam, combustion, and electrical motors had all been attempted. By the 1900’s it wasn’t very clear on which type of engine would really power the automobile. At that time, electric cars were the most popular but there were no batteries at that time that would allow a car to move very fast or a long distance. Commercial production in the United States began at the beginning of the 1900’s. In the early 1900’s, the United States had about two thousand firms producing one or more cars.
The Steam Engine “In the never-ending search for energy sources, the invention of the steam engine changed the face of the earth.” (Siegel, Preface) The steam engine was the principal power source during the British Industrial Revolution in the 18th century. The steam engine opened a whole new world for everyone. The steam engine maximizes production, efficiency, reliability, minimizes time, the amount of labor, and the usage of animals.
refined in the 1930's when the turbine engine design lead to the patent of the
The jet engine is a great mechanical piece of engineering. It has been used in almost all aircraft since its invention. This one improvement in aircraft allowed aircraft to fly higher, faster, and more efficient. The turbocharged engine invented by GE was the main building block for other engines. Since its invention, the jet engine has been the workhorse for all jet powered aircraft.
The invention of internal combustion engines in the early 19th century has led to the discovery of utilisation of cheap energy that is petroleum and this enabled the world to develop and progress into the modern world today. Humans were able to accomplish more work done with little manual labour, using internal combustion engines powered by fossil fuels. Internal combustion engine are mechanical power devices that convert heat energy to mechanical energy with the combustion process taking place in a system boundary (Rolle, 2005). Among the internal combustion engine invented in the 19th century were the Otto engine, Diesel engine and gas turbine engine. Gas turbine engine is one of the popular engines used today due to its high torque per weight ratio relative to other types of internal combustion engines. As explained by Cengel and Boles (2011), the gas turbine engine works on a 6 stages process, namely air intake, compression, fuel injection, combustion, expansion and exhaust (refer to Figure 1 in Appendix 1).
329) There was not one specific person who "invented the automobile," but, there were many people who contributed to the invention of the automobile.(Ingrassia, 5) (Boyne, 31) These people include Isaac Newton, who developed a power carriage in the fourteen twenties, and Joseph Cugnot, who built the first steam powered automobile in seventeen sixty nine. The first American to develop an automobile was Nathan Redd.(Brown, 329) The use of the automobile in the United States became common due to the convenience and reliability of a quick, easy to operate source of transportation. The American people began to build their homes further from their jobs, and further from civilization because they could commute back and forth much more quickly.(Simanaitis, 337) The convenience, reliability, and easy commute were only a few positive effects of the development of the automobile in the United States. The invention of the automobile also directly stimulated the economical growth and success of the United States.
Before the invention of the modern day engine, lifestyles were completely different. Letters were sent by horse drawn wagons, people traveled by horses and other such animals, often taking an entire day to go twenty miles. The first direct injection fuel engine was not invented until 1923.[1] It only took a year before this engine was put into automobiles, making the lives of the general public much easier. The invention of the engine not only made it possible to travel by road, but also by water and air. Mail was no longer delivered by horses and families were able to travel from one place to another in less than an entire day. However, the affects of the modern day engine can be seen all over the world. Take Los Angeles for example; the city is filled with smog which is from the overcrowding of all the freeways with automobiles. Technology has escalated to a level where engines are no longer made by the working man. Now, engines can be made simply machines and computer based tools. However, these thought of simple ways of creating engines are not as easy as the first seemed. There are many positive and negative aspects of using technology to design engines.
Diesel engines are an important component of society in how they are used efficiently and effectively. Diesel engines have been around since 1892 when inventor Rudolph Diesel was able to achieve his goal of developing an internal combustion engine that can achieve maximum efficiency as seen in the Carnot Theorem. The Carnot Theorem set the standard for determining the maximum
Cars are the ultimate symbol of independence and individualism. They offer more than freedom. No other man made creation but car fulfills a man’s ego. Technology has been the evidence of how cars have evolved for about more than a century now. From a first car packing a single cylinder 958cc, 0.75hp engine to today’s most powerful 8000cc W16, 1300bhp Veyron. We live in such an engineering savvy era where even an increase of few grams in a vehicle’s weight means going back to the drawing board to get unerring dynamic performance. And for these exuberant reasons, mechanical engineering was a mere choice rather than a chance for me.
When technology solves one of our problems we keep immediately coming up with new, larger problems, no technology will ever be able to satisfy our constantly new needs. However, if we allow technology to make our life easier, and focus more on the quality, rather than the quantity of life, and also learn how to use technology to our greatest advantage such as how to use it to influence others we can all greatly benefit. For example, the invention of the car allowed us to save time, when compared to walking. However, it also made us want to go further by giving us this option, so overall we spend more time getting to places. The same is true for other technologies we want to travel to more countries, learn more. The search for experience has become the meaning of life for many. The technology we are surrounding ourselves with is designed to give us more time for ourselves, which is something we all want. However, today, while technology is as developed as ever before, we are living in a time with the biggest scarcity of time. People are trying to live 10 lives at once and a lot of stress and anxiety occurs from
