Automobiles are vehicles that provide the means of transportation for passengers and cargo. They are a key component of our society and economy. A robust auto manufacturing sector is critical to the American economy and supports jobs across America.
Automobile is a French word, coming from auto–engine– + mobile (from Latin mobili-car). It first appeared in the 19th century and was applied to vehicles powered by engines instead of pulled by horses. The automobile revolutionized society and changed the way we live and work. It opened up new career possibilities and allowed people to travel and explore. People who had previously relied on public transportation could escape from urban life and enjoy the country, while those living in rural areas could visit cities to shop and socialize.
One of the most significant changes in the history of automobiles was the invention of the assembly line. This made it possible to build cars at much lower prices and sell them to a wide range of people. This allowed more people to afford cars and increased car use. The development of the automobile also created new industries that produced components such as tires and engines, and it led to the growth of services such as gas stations.
The SAE (Society of Automotive Engineers) sets most of the industry standards for testing and designing automotive-industry products. It is an international professional association with over 550,000 members worldwide. The organization is known for its standards and publications, which help to ensure that the vehicles we drive are safe, durable, and comfortable.
Its members are engineers, technicians, and other professionals who design, test, and analyze vehicles and their components. The group also publishes the Manual of Automotive Engineering, which is used by engineers, technical writers, and others in the automotive industry.
Using thin, carefully shaped and joined panels rather than a framework of thick members, the body of an automobile is often called unitized construction. This body construction method makes it possible to create a light, strong, and economical vehicle. It is used on luxury and sports cars as well as on commercial and utility vehicles.
An articulating shaft used in independent-suspension systems to transmit power from the differential to the wheel. The shaft is supported by ball bearings on a recirculating track to reduce friction. It may also be referred to as a sway bar.
A measurement of engine speed, usually indicated on a tachometer by a colored sector or line. The redline is the maximum recommended rpm for the engine. It is important to stay below the redline to prevent damage to the engine, transmission, and other components of the car.
The SAE publishes many publications that are useful to the automotive industry, including technical standards for brakes and other vehicle components. It also has a number of training courses available to members. These courses can help to improve the quality of the cars that are built in the United States. The organization also aims to increase awareness of the benefits that come with a clean, energy-efficient, and safe motor vehicle fleet.
