Coefficient of limiting friction class 11

WebThe laws of limiting friction are given below. 1. The limiting friction depends upon the roughness or smoothness of the surfaces in contact and acts tangentially to the interface between them. 2. The direction of force of friction is always in a way that it opposes the direction of the motion. 3. Webcoefficient of friction, ratio of the frictional force resisting the motion of two surfaces in contact to the normal force pressing the two surfaces together. It is usually …
