What is an inclined plane?

What is the mechanical advantage of an inclined plane as a machine when inclination of the plane is 30^(@) with the horizontal , if the force acts (i) horizontally,(ii) along the plane ? What force along the plane is needed to raise a scooter of weight 150 kg ?

A particle is attached with a string of length l which is fixed at point O on an inclined plane what minimum velocity should be given to the particle along the incline so that it may complete a circle on inclined plane ( plane is smooth and initially particle was resting on the inclined plane . )

An ice cube is kept on an inclined plane of angle 30^(@) . The coefficient to kinetic friction between the block and incline plane is 1//sqrt(3) . What is the acceleration of the block ?

A block is placed on an inclined plane. The angle of inclination of the plane is such that the block slides down the plane at a constant speed. The coefficient of kinetic friction is

A cube of side a is placed on an inclined plane of inclination theta . What is the maximum value of theta for which the cube will not topple?

A cannon of mass M located at the base of an inclined plane, shoots a shell of mass m in a horizontal direction with velocity v. To what vertial, heigh does the cannon ascend the inclined plane as a result of recoil, if the angle of inclination of the plane if alpha and the coefficient of friction between the cannon and the plane is mu.

By increasing the angle of inclination, the M.A. of an inclined plane
