Question

tractors have large tyres , bulldozers have caterpillar tracks and heavy buses / trucks have eight rear wheels . give one reason common to all those

Answer 1

Answer:

It is due to pressure

Explanation:

Heavy vehicles such as tractors have large tires to increase the surface area because more the surface area less the pressure acts on the ground hence with the help of large tires the tractor does not sink into the ground and helps it stay on the surface , the same will act on bulldozers which have caterpillar tracks even they too increase the surface area and does not let it sink into the ground. Heavy buses have eight rear wheels so that they also increase the surface area and help it to stay on surface.
