Description

Friction: The tendency to oppose the relative motion between two surfaces in contact is called friction.

The limiting value of friction is also known as the minimum force of static friction that is required to move the body from rest.

The limiting friction is directly proportional to the normal reaction, R, which is given by the total weight W and R for horizontal surface.

Therefore,

The ratio of the limiting magnitude of the limiting friction (FL) to magnitude of the normal force (R) is constant known as the coefficient of limiting friction (μL).

The limiting friction depends on the nature and state of the two surfaces in contact and is independent of the surface in contact as long as the normal reaction remains constant.
