Define coefficient of static friction.

If the angle of inclination of the inclined plane is sin^(-1) ((1)/(2)) when the body just starts sliding find the angle of repose and coefficient of static friction between the body and the inclined plane.

A block of mass 4kg rests on a rough horizontal plane. The plane is gradually inclined until at an angle theta=60^(@) , with the vertical, the mass just begins to side. What is the coefficient of static friction between the block and the plane?
