Banking of a Road Surface
in a Straight line on a Horizontal Surface
Turning on a Horizontal Surface
Turning on a Banked Surface
Angle of Banking
The magnitude of the horizontal component of the normal reaction is
This force causes the centripetal acceleration, so, the magnitude of RH is also given by
The vertical forces acting on the vehicle are in equilibrium.
Therefore, considering magnitudes only
Dividing equation 1 by equation 2 gives:
This equation allows us to calculate the angle needed for a vehicle to go round the curve at a given speed, v, without any tendency to skid.
