Question

Definition of banking of roads?????​

Answer 1

pls Brainliest Me..

Banking of roads refers to the concept that the surface of the road is inclined with the horizontal. This angle is known as the angle of inclination or the angle of banking. When the road is banked the normal force provided by the road on the car provides a component which is in the direction of the centripetal force.

Banking of road means raising the outer edge of the road with respect to inner edge so that the road makes an angle with the horizontal.

When a vehicle moves along a curve, the force of friction provides the necessary centripetal force. But this force has a limit = μmg.When the speed of the vehicle increases beyond this maximum value, the banking of roads is necessary so that the component of normal reaction of the road towards the centre provides the necessary centripetal force.

From the figure, for vertical equilibrium :

Total upwards force = total downwards force

Ncosθ=mg+fsinθ

mg=Ncosθ−fsinθ...(1)
