Materials Used in Car Construction
The cars we drive are a key part of our daily lives. Millions of people work in the factories that produce them and many more are employed at gas stations, restaurants or motels that travelers stop at. Cars make it easy to travel between cities and across continents. But they also cause problems such as road congestion, air pollution and the need to find parking space. Cars are complicated machines and all systems work together to power the engine, control and steer them and keep them comfortable for passengers. The materials that are used in the construction of a car can make it more efficient or less so. Using materials that are abundant, easy to obtain and simple to form can help a car be more economical and leave a smaller footprint on our heavily interconnected planet.
The term “car” is often used to describe any vehicle that moves on four wheels and carries people, but it has a specific meaning in the automotive industry. Karl Benz, a German engineer, invented the first motor car in 1885 and named it the Motorwagen. Other engineers and inventors followed with their own versions, but it was Henry Ford who revolutionized the way cars were made. His assembly line allowed him to produce lots of cars quickly. He also added features like seat belts and air bags to protect passengers in crashes.
Since the 1970s many automakers have tried to reduce the amount of fuel their vehicles use. They have done this by producing compact cars that are easier to handle and by adding more fuel-efficient engines. They have also tried to reduce the amount of greenhouse gases their cars release. They have accomplished this by reducing the weight of the vehicle and by using lighter, more energy-efficient materials to construct the body and chassis.
A car is a complex machine and all its parts must be in good working order for it to operate properly. The most important component is the engine, which produces the power that drives the wheels and generates electricity for lights and other functions. It’s also important to use materials that will not degrade over time, especially the tires and brakes.
In addition to a reliable engine, cars need strong and durable frames to support the vehicle and to withstand collisions with other vehicles and obstacles on the roadway. Steel is the most common material in vehicle construction, but some manufacturers use complex structural composites and plastics. These materials and the way they are fastened preserve body rigidity while allowing for a lightweight design that increases fuel economy.
Almost all cars run on gasoline, and it comes from oil. The oil supply in the United States and in other countries is limited. This has caused long lines at gas stations and high prices for consumers. Some car makers have developed hybrid, electric and compressed natural gas vehicles to limit their dependence on gasoline. However, these types of vehicles may not be a fit for every driver because they have limited range and/or cost more than other vehicles.
