ularto the plane and is called thenormal reaction. The other,F, is along the plane and iscalled the frictional force. The normal reaction is due to the rigidity of the plane. It re-sists the tendency of the body to go through the plane. Thefrictional force is due to the roughness of the contact… … Fig 22 ANALYTICAL MECHANICS when the equilibrium is disturbed and the body begins toslide down the plane. This angle is called the angle offriction. This definition for the angle of friction does nothold when the body is acted upon by other forces besidesits weight and the reaction of the plane.…
