Question

What is bankind of road? Why
is it necessary

Answer 1

Answer:

Banking of roads is defined as the phenomenon in which the edges are raised for the curved roadsabove the inner edge to provide the necessary centripetal force to the vehicles so that they take a safe turn. 

Answer 2

Answer:

• Banking of road is the process of raising outer edges of a road over its inner edge through certain angle.
• When a vehicle moves on a curved horizontal surface, friction force between wheels and road provides thenecessary centripetal force.
• When the road is banked, the horizontal component of the normal reaction provides the necessary centripetal force required for circular motion of vehicle. vi.
• Thus, to provide the necessary centripetal force at the curved road, banking of road is necessary
