Question

what is limiting friction? state the laws of limiting friction?​

Answer 1

Answer:

Explanation:

The maximum friction that can be generated between two static surfaces in contact with each other. Once a force applied to the two surfaces exceeds the limiting friction, motion will occur. For two dry surfaces, the limiting friction is a product of the normal reaction force and the coefficient of limiting friction.

Laws of limiting fraction are:

(a) The direction limiting frictional force and the direction of motion is always the opposite.

(b) The limiting friction always acts tangential to the two surfaces that are in contact.

(c) The magnitude of the limiting friction and the normal force between the two surfaces are directly proportional.
