Question

Explain the need for banking of tracks.

Answer 1

Answer:

When a vehicle moves on a curved horizontal surface, friction force between wheels and road provides the necessary centripetal force. ... To eliminator this difficulty, roads are banked. When road is banked, the horizontal component of normal reaction provides necessary centripetal force required for circular motion.

Answer 2

When the road is banked, the horizontal component of the normal reaction provides the necessary centripetal force required for circular motion of vehicle. ... Thus, to provide the necessary centripetal force at the curved road, banking of road is necessary.
