Question

Explain the need of banking of tracks??????????​

Answer 1

Answer:

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.

.......................

Answer 2

Answer:

When a vehicle moves on a curved horizontal surface, friction force between wheels and road provides the necessary centripetal force. But friction force is enough sometimes like during rain as road is oily. Road should be made through then but it cause wear & tear of tyres. When centripetal force is less the vehicle skid. 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.

So, roads are banked to provide necessary centripetal force.
