Railway tracks are banked on curves
necessary centrifugal force may be obtained from the horizontal component weight of the train
to avoid frictional force between the tracks and wheels
necessary centripetal force may be obtained from the horizontal component of the weight of the train
the train may not fly off in the opposite direction

Because to get centripetal force.

Its simple thing, i.e. whenever trains travel at high speed it requires to c turn then train pulls away from the centre of the curve by centrifugal force it can be balanced by centripetal force by providing banking means elevating track one side delivering in on the side.

Thank you all. Your responses are helpful.

There are two opposing forces acting on any object moving in a circular path. The first one is called centripetal force while the second is centriugal force. Centripetal force acts toward the centre of a cicular path while centrifugal pull a moving object away from the centre of the cicular path. Banking is the process of reducing centrifugal force and then increase centripental to prevent accident. Hope this help.

I can't understand the question. Can anyone give me the clear explanation?

@Dinesh and @Sandeep.

Your explanation is well. Thank you.

Banking means to raise the outer edge with inner edge of a road or track while following a curve.

Dede said:   1 decade ago
Tan of the angle at which the road is banked equals the mass multiplied by the square of the velocity all divided by the radius.

This centripetal force is needed to to avoid accident.

What is banking?
