Answer 1

Question:

• what is banking of road?

Answer:

• Banking of roads is defined as the phenomenon in which the edges are raised for the curved roads above the inner edge to provide the necessary centripetal force to the vehicles so that they take a safe turn. Another terminology used is banked turn which is defined as the turn or change of direction in which the vehicle inclines towards inside. The angle at which the vehicle is inclined is defined as the bank angle. The inclination happens at the longitudinal and horizontal axis.

Question:

• why it is necessary​

Answer:

• Banking of roads is needed to increase safety while taking a turn. To obtain an expression for the maximum speed first draw all the forces acting on a vehicle taking a turn on the banked road. Resolve all the forces in the horizontal and vertical components. Equate the net force in the vertical direction to zero.
