Banking of Roads

While riding a bicycle and taking a sharp turn, you may have felt that something is trying to throw you away from your path.

You tend to be thrown out because enough centripetal force has not been provided to keep you in the circular path. Some force is provided by the friction between the tyres and the road, but that may not be sufficient. When you slow down, the needed centripetal force decreases and you manage to complete this turn.

Consider a car of mass m, travelling with speed v on a curved section of a highway. To keep the car moving uniformly on the circular path, a force must act on it directed towards the centre of the circle and its magnitude must be equal to mv2/r.

If the road is levelled, the force of friction between the road and the tyres provides the necessary centripetal force to keep the car in circular path. This causes a lot of wear and tear in the tyre and may not be enough to give it a safe turn. The roads at curves are, therefore, banked, where banking means the raising of the outer edge of the road above the level of the inner edge.



Aircrafts in Vertical Loops

In situations pilots where pilots fly aircrafts in loops, at the bottom of the loop, the pilots feel as if they are being pressed to their seats by a force several times the force of gravity. The forces acting on him are mg and the normal force N exerted by the seat. The net vertically upward force is N – mg and this provides the centripetal acceleration.
