Question

What is the banking of roads? Why is banking necessary for a curved road?

Answer 1

Banking of roads:

The process of raising the outer edge of a road over its inner edge by certain angles is known as banking.

Banking is necessary for a curved road because:

1. When a vehicle travels on a curved horizontal surface, the friction force between the wheels and the road provides the required centripetal force. However, the friction force is sufficient in some situations, such as when it rains and the road is oily.
2. The road should be built through there, but it causes tire wear and tear.
3. The vehicle skids when the centripetal force is low.
4. Roads are banked to eliminate this difficulty.
5. When a road is banked, the horizontal component of the normal reaction provides the required centripetal force for circular motion.
   As a result, roads are banked to provide the required centripetal force.
