Automobiles are motor vehicles with four wheels that can transport passengers. They run primarily on roads and carry one to eight people. They can also carry cargo but are usually designed to transport passengers. The branch of engineering that deals with the manufacturing and technology of automobiles is called Automotive Engineering. Automobiles have become an integral part of our daily lives, and it is hard to imagine a world without them.
Pros: Automobiles are far faster than walking or riding a bike if you have to go a long distance, and they can carry more luggage. They are also good at reaching places where public transportation cannot. They can often be cheaper than using buses or trains.
Cons: Automobiles are very polluting and generate greenhouse gases. They emit 27 percent of the carbon dioxide in the United States, according to the Environmental Protection Agency. It is possible to limit this by driving an energy-efficient car and keeping it well maintained. Also, cars consume a lot of oil, which is in short supply.
The earliest automobiles were steam-powered, but they soon gave way to the internal combustion engine vehicle. The first gasoline-powered automobiles were built in the late 19th century, and by 1920 they had overtaken the streets of Europe and America. In the 1920s, Henry Ford revolutionized automobile production with his assembly line and made them affordable for middle-class families.
A modern automobile consists of various parts, including the chassis/frame, engine, transmission, clutch and fluid coupling. The chassis/frame holds the various components/sub-assemblies together correctly. The engine produces the power that drives the wheels. This power is transferred to the wheels by the transmission, which consists of a clutch and a gearbox. The clutch is used to disconnect the drive shaft from the driven shaft when it is not needed. The gears are used to adjust the speed and torque, which are inversely proportional.
Safety: Automobiles have many safety features, including seat belts, air bags and crash-testing. However, it is important to remember that driving a car is a dangerous activity and accidents can happen. Injuries and deaths caused by automobiles can be severe. There are many types of injuries that can be sustained in an accident, and these include burns, fractures, spinal cord injuries and head trauma.
The most common type of injury in an automobile accident is a head trauma, which can be very serious and sometimes even life-threatening. The severity of the head trauma can depend on how fast the car was traveling at the time. Other injuries may include broken bones, traumatic brain injury and internal organ damage. Some injuries may be permanent, and some may be disfiguring or crippling. The most serious injuries are those that cause paralysis and loss of consciousness. These injuries can have a devastating effect on the victim and his or her family. In addition, they can also affect the quality of life for a long period of time and cause significant financial losses.
