Why a wide steel belt is provided over wheels of an army tank?

A wide steel belt is provided over the wheels of an army tank to distribute the weight of the tank over a larger surface area, thereby reducing the ground pressure. This is important because it prevents the tank from sinking into soft ground, such as mud or sand. Additionally, the wide steel belt helps to create a smoother ride for the tank, which is important for the comfort and safety of the crew.

Here are some specific advantages of using a wide steel belt over wheels for an army tank:

* Reduced ground pressure: The wide steel belt distributes the weight of the tank over a larger surface area, which reduces the ground pressure exerted by the tank. This is important because it prevents the tank from sinking into soft ground, such as mud or sand.

* Smoother ride: The wide steel belt helps to create a smoother ride for the tank by absorbing vibrations and bumps from the ground. This is important for the comfort and safety of the crew.

* Improved traction: The wide steel belt provides better traction for the tank, which is important for climbing hills and moving through difficult terrain.

* Protection from damage: The wide steel belt can help to protect the tank's wheels from damage, such as from rocks or other obstacles.

Overall, using a wide steel belt over wheels provides several advantages for army tanks, including reduced ground pressure, a smoother ride, improved traction, and protection from damage.
