The Advantages and Disadvantages of Automobiles
Automobiles are motorized vehicles that have four wheels and are powered by an internal combustion engine. Most automobiles use gasoline, but diesel engines are also common in some countries. The engine is the primary source of power for an automobile, but it requires a starter motor to start, and a battery or alternator to provide energy for systems such as braking and steering. The chassis and body, analogous to the skeletal system of the human body, support the engine and other components and protect passengers from the elements.
OPENS UP THE WORLD: The automobile is an important social development because it allows people to travel long distances quickly. This opens up new possibilities for work, housing and relationships. It enables people to live in a place that is remote or isolated and still be close to family, friends and colleagues. In addition, a car can make trips to the store or shopping mall much easier and quicker.
Most people have busy lives, and an automobile can help them save time by reducing the number of trips they need to make. Having a car also means that people can go places on weekends or after work without having to rely on others for rides. Having a car can allow people to spend more time doing the things that they enjoy, whether it is playing sports, visiting with friends or family or attending other events.
A CON: Automobiles are often polluting, and most of them run on fossil fuels. This releases carbon dioxide, a greenhouse gas, into the air. This is bad for the environment and can lead to global warming. However, the good news is that there are ways to reduce these emissions by driving a car that gets great mileage and keeping it well-maintained.
The Automobile industry is one of the fastest growing in the world. New technology is constantly being used to improve the performance, comfort, safety and appearance of cars. Several research and development engineers and scientists are employed by the different automobile manufacturers and suppliers to develop and test prototypes of new engines, chassis, suspension systems, braking systems, electrical systems, computer control systems, safety systems and air-conditioning systems.
The history of the modern automobile began with the Benz Patent-Motorwagen, invented by Karl Benz in 1886. It was the first automobile to use an internal combustion engine instead of being pulled by a horse. Most modern automobiles use a four-stroke type of internal combustion engine that uses gasoline, diesel fuel or kerosene to produce the energy needed to turn the vehicle’s wheels. This energy is transferred to the wheels through a transmission system and an axle assembly. The tires on the wheels are connected to the axle assemblies by a suspension system that consists of shock absorbers and springs. The tires are designed to grip the road and guide the automobile over turns. The wheels are also connected to the axle assemblies by a brake system that uses friction to stop the automobile.
