Question

What are the laws of Limiting Friction

Answer 1

What is limiting friction?

$\implies$ Limiting friction is the maximum value of static friction which comes which works when a body slides over the surface of other body.

Laws of limiting friction :-

• The direction of the force of limiting friction is always opposite to the direction in which one is at the verge of moving over the other.

• The magnitude of the force limiting friction (F) between any two bodies in contact is directly proportional to the normal reaction (R)

$\: \: \: \: \: \: \: \: \: \: \: \: F \infty R$

• The force of limiting friction is independent of the apparent area of contact, so long as normal reaction between the two bodies in contact remains the same.

• The force of limiting friction between any two bodies in contact depends on the nature of material of the surface in contact.

Answer 2

$\huge\tt\pink{Answer:-}$

The laws of limiting friction are given below.

• The limiting friction depends upon the roughness or smoothness of the surfaces in contact and acts tangentially to the interface between them.

• The direction of force of friction is always in a way that it opposes the direction of the motion.

• It is independent of area and shape of the surface in contact as long as the normal reaction remains the same.

• It is directly proportional to the normal reaction between the two surfaces in contact.
