Banking Of Roads

State the laws of friction. Obtain an expression for the best speed at which to take the curve on a banked road having friction.

Why is banking done in road?

Banking of road helps to increase the centripetal force and thereby increases the limit of maximum speed of vehicle with it can take the curve. Give the expression for the maximum allowed speed of a vehicle on a banked road with friction.

A circular curve of a highway is designed for traffic moving at 72km//h . If the radius of the curved path is 100m , the correct angle of banking of the road should be given by :
