Question

what is bending of cyclists

Answer 1

In order to take a safe turn, the cyclist has to bend a little from his vertical position. In this case, a component of the reaction provides the required centripetal force.

If q is angle made by the cyclist with the vertical then


In actual practice, the value of q is slightly less because the force of friction also contributes towards the centripetal force.
