Automobiles and Their Impact on Society
Automobiles are powered by internal combustion engines, usually gas or diesel fueled. The engine is located in the front of the vehicle and either drives the front wheels or the rear wheels or both. The power of the engine is transmitted through gearing or by a clutch to the drive shaft which in turn powers the wheels. Some models have a gasoline-fueled electric motor which can also be used as a backup. Most modern automobiles use a liquid-cooled piston-type internal combustion engine fueled by gasoline or diesel fuel.
Automobiles have had a profound impact on society and culture, changing people’s lifestyles, work patterns, and social interaction. Cars make it possible for people to travel long distances without spending a great deal of time in transit, and to reach destinations more quickly than was once feasible. Without the ability to easily commute, it would be impossible for many people to hold jobs and live a full life outside the home, particularly those who live in rural areas or in cities far away from employment opportunities.
Having your own automobile means you have the flexibility to decide where and when to go, based on your needs at any given time. It also eliminates the need to rely on others for transportation, and gives you the freedom to take detours and find alternative routes when needed. You can travel to visit friends and family at a moment’s notice, or run errands such as grocery shopping and paying utility bills.
It’s difficult to pinpoint exactly who invented the first automobile, but history credits Karl Benz with creating one in 1885. Benz’s design was an improvement over previous steam, electric, and horse-drawn carriages that had been used since the 1600s. He designed his Benz Patent-Motorwagen with a four-stroke type of internal combustion engine and manufactured them in small numbers at his factory in Germany.
The American businessman Henry Ford came into the picture around 1910 and made a big contribution to automobile production. He realized that if he could improve the manufacturing process, he would be able to produce cars at a much lower cost. By using the assembly line to manufacture one model with basic features, he was able to turn out vehicles faster and cheaper so that more people could afford them.
As automobiles have become more sophisticated, they have evolved to meet new technical challenges, such as safety systems and emission controls. Engineering teams have been constantly improving the body, chassis, and engine of vehicles to ensure they are safe and economical to operate. The development of new materials for the bodies, including steel section pillars and structures paired with aluminum panelling, have contributed to the growing popularity of light-weight automobiles that are both sleek and durable.
Although cars offer people a great deal of convenience, they have their drawbacks. Automobiles can cause air pollution when too many of them are on the road at the same time, and their consumption of fossil fuels is putting a strain on dwindling world oil supplies. In addition, accidents involving automobiles can cause serious injuries to passengers and damage to property. For these reasons, many cities and countries have created public transportation systems that provide quicker and cheaper alternatives to traveling by automobile when congestion is an issue.
