Question

Explain

Why do the army tanks move over the wide steel chain rather than on the wheels?

Answer 1

because they are very heavy nd wheels don't hve that much capacity tu hold the weight of tanks.

Answer 2

Answer:

same reason that the agricultural and construction tractors, which the first tanks were developed from, used tracks rather than wheels: mobility in challenging terrain. The ground-pressure of a tracked system is so vastly more distributed than a wheeled system, that a tracked vehicle can get across soft turf, mud, and crumbly soil that would bog down any vehicle with wheels, no matter how big or well-designed.
