Answer» Banking of road is done to ensure the safety of cars on curved roads. As the speed of the vehicle increases, the centripetal force required for circular motion also increases. The maximum speed of the vehicle depends only on the coefficient of friction between the wheels and road. However, the friction coefficient reduces if the roads are wet or cover with oil. Thus, to increase the safety of the vehicle, the outer edge is raised above the inner one, making an inclination with the horizontal. The banking of road provides the necessary centripetal force for the motion of the vehicle on curved roads. |
