A cyclist leans inwards when he is negotiating a curve so that
He may increase his speed
His weight may be reduced
Necessary centripetal force may be available from the horizontal component of the normal reaction due to the track to maintain the curved motion.
No frictional force may be produced between the wheels and the axle
Necessary centripetal force may be available from the horizontal component of the normal reaction due to the track to maintain the curved motion.
The weight W, acts vertically downward and the normal force, N acts vertically upward. The frictional force, F, of the road acts horizontally in the direction of which the cyclist is turning. The frictional force provides the centripetal force necessary to turn the cyclist. But the frictional force also produces a torque that will cause the rider and bicycle to tip outwards. When the cyclist lean inwards the normal force of the road does not act through the center of gravity thus producing an opposite torque that cancels out the torque provided by the frictional force. Thus there is no tendency for the cyclist to tip outwards.
