Banking Of Roads

What is the need of banking a circular road ?

When a cyclist turns on a circular path,the necessary centripetal force is provided by friction between the tyres and the road. If centripetal force is not provided by friction, then for the vehicle to move on circular path, the track is banked. The correct angle of banking for a curved smooth road of radius 120 m for a speed of 108 km//h(g=10 ms^(-2)) is

For traffic moving at 60 kmh^(-1) , if the radius of the curve is 0.1 km , what is the correct angle of banking of the road? Take g = 10ms^(-2) .

A circular curve of a highway is designed for traffic moving at 72km//h . If the radius of the curved path is 100m , the correct angle of banking of the road should be given by :

A circular curve of a highway is designed for traffic moving at 72 km/h. if the radius of the curved path is 100 m, the correct angle of banking of the road should be given by:

The angle of banking of the road does not depend upon

For traffic moving at 60km//h if the radius of the curve is 0.1km what is the correct angle of banking of the road Given g = 10m//s^(2) .

Roads are banked on curves so that
