Question

While driving along an unbanked
circular rood, a two-wheeler rider has
to lean with the vertical. Why is it so?
With what angle the rider has to lean?
Derive the relevant expression. Why
such a leaning is not necessary for a four
wheeler?​

Answer 1

Answer:

A rider must lean into a turn to prevent tipping over in the other direction. To remain upright while turning to the left, there are three forces acting on the rider and bicycle. The frictional force provides the centripetal force necessary to turn the cyclist to the left.
