Question

How does banking of roads reduce wear and tear of the tyres?

CLASS - XI PHYSICS (Laws of Motion)

Answer 1

The magnitude of frictional force gets decreased by banking of the road than the horizontal road. Hence the wear and tear of the tyres will be less.

Answer 2

$\underline{\underline{\Huge\mathfrak{Answer-: }}}$

◆When a curved road is unbanked, force of friction between the tyres and the road provides the necessary centripetal force. Friction has to be increased suitably, that will cause wear and tear. However, when the curved road is banked, a component of normal reaction of the ground provides the necessary centripetal force. Therefore, wear and tear of the tyres is reduced.
