When vehicle go through turnings, they travel along a nearly circular arc. There must be some force to produce the required centripetal acceleration. Centripetal force is provided to the vehicle by following three ways.
By banking of roads only:
To avoid friction outer part of road is some what lifted compared to the inner part.
Fig (29)
From figure (29) NSin
= 
and NCos = mg
From this we get, Tan = 
At two speeds car does not slide down even if track is smooth.

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
