Why are curved roads banked ?

The maximum speed with which a vehicle can negotiate a cuved road, which is banked at the angle theta=tan^-1(0.24) is 54 km//hr . IF the same road is flat and vehicle has to negotiate the curve with same maximum speed, the coefficient of friction between the road and tyres of the vehicle should be

For a banked curved road. The necessary centripetal force or any vehicle is provided by

Derive an expression for most safe speed of a vehicle on a curved banked road ignoring friction.

The angle of banking theta is independent of mass of vehicle dependent on speed of vehicle dependent on radius of curvature of curved road The correct statement(s) is/are

The safe speed of a vehicle on a horizontal curve road is independent is

Radius of the curved road on national highway is r. Width of the road is l. The outer edge of the road is raised by h with respect to the inner edge so that a car with velocity v can pass safely over it. The value of h is

What will be the maximum speed of a car when it is safely driven along a curved road of radius 100 m ?

The curved horizontal road is banked at an angle theta . What will happen to a vehicle moving along this road if : theta'>theta . Where theta is the angle of banking for given road.

The curved horizontal road is banked at an angle theta . What will happen to a vehicle moving along this road if : theta' < theta . Where theta is the angle of banking for given road.
