A body is in equilibrium on a rough inclined plane undr its own weight. If the angle of inclination of the inclined plane is `alpha` and the angle of friction is `lambda`, then

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

A body takes ''n'' times as much time to slide down a rough inclined plane as it takes to slide down an identical but smooth inclined plane. If the angle of inclination of the inclined plane is ''theta'' . What is the coefficient of friction between the body and the rough plane ?

If the angle of inclination of an inclined plane of 30^(@) , its mechanical advantage is ______

When a body is lying on a rough inclined plane and does not move, the force of friction

Assertion: A body slides down an inclined plane if the angle of friction is more than the angle of the inclined plane with the horizontal. Reason : When the angle of inclination is equal to the angle of friction, the component of weight parallel to the plane is just sufficient to overcome the frictional force.
