Banking of roads is used to help prevent vehicles from skidding off the road when they are going around curves. It works by creating a force that pushes the vehicle inward toward the center of the curve. This force is called centripetal force.
The amount of banking needed depends on the speed of the vehicles that are expected to travel on the road and the radius of the curve. If the banking is too excessive, it can cause vehicles to lean over too far and this can put stress on the tires and suspension system.
Additionally, banking of roads can lead to uneven wear on tires, as the tires on the inside of the curve will be doing more work than the tires on the outside of the curve.
For these reasons, it is important for road engineers to carefully consider the amount of banking that is used on curves.
