What materials are used to make a bus?

Answer 1

The most important raw material used to manufacture school buses is steel, which is an alloy of iron and a small amount of carbon. Steel is used to make the chassis and the body, along with various other components. Steel is made from iron ore, coke (a carbon-rich substance produced by burning coal in the absence of air), and limestone. The coke provides the carbon, which transforms the iron into steel, and the limestone reacts with impurities in the ore to remove them in the form of slag. Oxygen is then blasted into the molten mixture to remove excess carbon and other impurities. The windows of a school bus are made of laminated glass. Laminated glass consists of two layers of glass surrounding a layer of plastic. The plastic holds the glass in place if the window is broken, adding to its safety. The tires of a school bus are made from a mixture of natural or synthetic rubber, carbon black, sulfur, and other chemicals, which determine the characteristics of the tires. Natural rubber is obtained from latex, a liquid produced when the bark of a rubber tree is cut. Synthetic rubber is produced from chemicals obtained from petroleum. Carbon black is made by burning petroleum or natural gas in a limited supply of air, resulting in a large amount of fine soot. Other raw materials used in school bus manufacturing include various metals and plastics. These are used to make the many small parts, which are assembled together with the chassis and the body to make up the completed vehicle.
