Automobiles are self-propelled cars that use a motor to move. They have four to eight tires & can be powered by an internal combustion engine or electric motor.
The branch of engineering that deals with the manufacture and technologies of automobiles is known as automotive engineering. Today automobiles play a major role in the world and cannot be imagined without them. The automobile has opened up many vistas for human travel. People now have the freedom to visit places in a short time and enjoy their vacations with family and friends. It has also increased work possibilities & made it possible for people to choose where they want to live in relation to their job.
Karl Benz, a German engineer, is credited with inventing the first modern automobile in 1885. Several inventors and engineers worked on improving the design until Henry Ford revolutionized how the automobile was manufactured. His idea of using the assembly line allowed him to produce automobiles at a lower cost so that more people could afford them. Most automobiles are powered by an internal combustion engine that burns gasoline, diesel fuel, or kerosene. The explosion of the fuel in the cylinder pushes down the piston and drives the wheels, which make the automobile move.
The automobile has had many social effects, including allowing city dwellers to see pristine countryside and rural dwellers to shop in cities. The automobile has also encouraged family vacations, expanded dating opportunities, and aided in the spread of religions and ideas. It has also caused problems, such as traffic jams and the need for licensure and safety regulations.
