Question

Why do the load carrying heavy vehicles have a large number of wheels?

Answer 1

hey here is ur answer

heavy load carrying vehicles have large no. of tires bcoz as the surface area is more the force will be less so they have many big tires

I hope you understood

Answer 2

Answer:

We know,

Pressure = Force / Area

When the area of contact between two surfaces is greater, the pressure will be less too. Hence, the load-carrying heavy vehicles usually have a greater number of wheels as there is a reduction in pressure on the road due to greater contact area. This happens as the load is equally shared among the tyres which ensures that the force caused is equally distributed among all the tyres and no single tyre is under tremendous pressure.
