Explain using pressure: Why do Bulldozers, caterpillar and heavy lorries have flat feet? |
|
Answer» A bulldozer or dozer (also called a crawler) is a large, MOTORIZED machine that travels on continuous tracks or large tires and is EQUIPPED with a metal blade to the front for pushing material: soil, sand, snow, rubble, or rock during construction or conversion work. When needed, a hook-like device (termed a ripper) can be mounted on the rear to loosen dense materials. Bulldozers can be found on a wide range of sites, mines and QUARRIES, MILITARY bases, heavy industry factories, engineering projects, and farms. The word "bulldozer" refers only to a tractor fitted with a dozer blade. The word is sometimes used inaccurately for other earth moving equipment such as front loaders.Explanation: |
