For a Vehicle taking turn on a Curved path, If It's velocity exceeds a certain value it may loose it's balace and skid due to a force called Centrifugal Force.To Avoid this it should be provided by necessary centripetal force. It is done by slightly rising outer edge of the road. This is known as banking of roads. The angle made by the surface of road with horizontal direction is known as angle of banking.For a Vehicle moving with a velocity 'V' on a curved path of radious 'R', the angle of banking 'θ' and Velocity of vehicle are Related as:
