A block is stationary on an inclined plane If the coefficient of friction between the block and the plane is mu then .

The minimum force required to move a body up an inclined plane of inclination 30° is found to be thrice the minimum force required to prevent if from sliding down the plane. The co-efficient of friction between the body and the plane is -

The minimum force required to move a body up on an inclined plane is three times the minimum force required to prevent it from sliding down the plane. If the coefficient of friction between the body and the inclined plane is 1/(2sqrt3) the angle of the inclined plane is

It takes a block twice as long to slide down a plane incline at 45^(@) to the horizontal as it would take for it to slide down the same plane had the plane been frictionless. Colculate the coefficient of friction between block and inclined plane.

A block placed on a rough inclined plane of inclination ( theta= 30^(@)) can just be pushed upwards by applying a froce "F"as shown. If the angle of inclination of the inclined plane is increased to ( theta = 60^(@)) , the same block can just be prevented from sliding down by application of a force of same magnitude. The coefficient of friction between the block and the inclined plane is

In the situation shown, the force required to just move a body up an inclined plane is double the force required to just prevent the body from sliding down the plane. The coefficient of friction between the block and plane is mu . The angle of inclination of the plane from horizontal is given by :

The force required just to move a body up an inclined plane is double the force required just to prevent the body sliding down. If the coefficient of friction is 0.25 , the angle of inclination of the plane is

Starting from rest , a body slides down at 45^(@) inclined plane in twice the time it takes to slide down the same distance in the absence of friction. The coefficient of friction between the body and the inclined plane is
