Question

In negotiating curve on a flat road, a cyclist leans inwards by an angle e with the vertical in order to ______.

Options

• counteract the torque of the frictional force that tends to topple him outwards

• counteract the centrifugal force.

• generate a centripetal force

• counteract the centripetal force with an equal centrifugal force

Answer 1

In negotiating curve on a flat road, a cyclist leans inwards by an angle e with the vertical in order to counteract the torque of the frictional force that tends to topple him outwards.

Explanation:

The frictional force between the tyres and the road produces the necessary c.p.f., but it also has a moment about the cyclist's centre of gravity, causing the cyclist to tumble.
