Question

what is banking of roads ?​

Answer 1

Answer:

Banking of roads is defined as the phenomenon in which the edges are raised for the curved roads above the inner edge to provide the necessary centripetal force to the vehicles so that they take a safe turn. ... The angle at which the vehicle is inclined is defined as the bank angle.

hope it helps.

Answer 2

Answer:

When the road is banked, the horizontal component of the normal reaction provides the necessary centripetal force required for circular motion of vehicle. vi. Thus, to provide the necessary centripetal force at the curved road, banking of road is necessary.

$v=\sqrt{\frac{(rg(tan\Theta+\mu_s))}{1-\mu_S\,tan\theta}}$
