Question

Explain, why a truck or a motor bus has much wider tyres?

Answer 1

1. Pressure and surface area are inversely proportional to each other.
2. The truck and motor bus have wider tires concerning the property that "more the area, less the pressure."
3. As the area is more, the pressure that the vehicle will exert on the ground will decrease which prevents it from sinking on a wet and muddy road.
4. Hence, the vehicle will move smoothly.
