Question

Why are caterpillar tracks used in battle tanks instead of tyres?

Answer 1

Caterpillar tracks are used in battle tanks instead of tyres because they considerably increase the area of contact. The larger the area of contact, the smaller the effect of force. Thus, a caterpillar track helps a battle tank in distributing its weight more evenly over a large surface area than wheels can. This prevents it from sinking in areas where wheeled vehicles of the same weight can easily sink.
