Question

Why is a wide steel belt provide with wheels of an army tank

Answer 1

The army tank is  very heavy. It has wide steel belt  over the wheels. The wide belts increase the area  and reduce the pressure . This  avoids sinking  of the tank into the ground.

Answer 2

Answer:

Explanation:The wide steel belt is observed over the wheels of the tanks of every army. The reason behind is the pressure management. As we know the pressure is force applied per unit area.  

The army tanks are much bulkier and have a tendency to be grounded if preventive measures were not taken. One such is the wide steel belt over wheels by which the surface area of the wheel portion is increased and as pressure is inversely proportional to surface area, pressure will decrease.  

This allows the army tank to move smoothly over the ground without being sunken in.

It once happened when a person invented a tank with wheels but it was observed to be slow and sunk in loose soil.

Steel belt also allows it to go faster.

It is proved by the equation P=F/A
