Question

Explain bending of a cyclists?​

Answer 1

Answer:

The torque due to the centripetal force is ( mv2/r BC) which causes an anticlockwise turn that is taken as positive. While negotiating a circular level road of radius r at velocity v, a cyclist has to bend by an angle θ from vertical given by the above expression to stay in equilibrium (i.e. to avoid a fall).

Answer 2

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.
