Usually defined as a wheeled motor vehicle, automobiles are designed to transport passengers or goods. They usually have four wheels and an internal combustion engine. Their main use is passenger transportation, but they can also be used for other purposes. They are used by billions of people every year. The automobile industry is one of the largest industries in the world.
Originally developed as bicycle-like contraptions, the automobile is an answer to a 19th-century dream: the self-propelling carriage. This technology has proven to be one of the most universal modern technologies. It has also had significant social and economic impacts on the world.
The first commercial three-wheeler was built in 1884 by Edward Butler. It featured a horizontal single-cylinder gasoline engine and a drive chain to the rear wheel. It was designed to be a commercial vehicle, but it was also intended to be a living area on wheels. It was also a precursor to the modern minivan.
As the automobile industry grew, it created a huge economic revolution in the United States. Automobiles were now affordable to the middle class. They also opened the doors to family vacations and shopping in towns. They also provided new social opportunities, such as a more relaxed sexual attitude.
In the 1920s, the automobile industry experienced a huge increase in demand. The automobile revolution led to the construction of thousands of new jobs. During this time, the automotive industry also experienced difficulties. The number of registered drivers tripled to 23 million by 1920. The 1920s also saw an explosion of traffic accidents, which led to a call for state-level safety regulation.
Automobiles are a complex technical system that employs thousands of component parts. The engine powering an automobile may be a gasoline or a diesel fuel, or it may be powered by an electric motor. It may also have many internal parts, which may be made of steel, petroleum, or other materials. The engine may be a two-stroke or a three-cylinder design. The size of the engine, the weight distribution of the vehicle, and the location of the engine influence stability.
