1.	Explain why a wide steel belt is provided over the wheels of an army tank.
Answer» Since `P=(F)/(A)`, the wide belt (large area A) over the wheels of an army tank reduces the pressure (P) exerted by the tank on the ground due to its weight (F) and this prevents the tank from sinking into the dround.
