Question

3 State laws of limiting friction. Define coefficient of
limiting friction.​

Answer 1

Answer:

Coefficient of friction, which applies to two bodies in contact that have not yet begun to move. Its value equals the maximum static friction divided by the perpendicular force pressing the two surfaces together (i.e. the normal reaction force). Compare coefficient of kinetic friction.

Explanation:

(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.

The coefficient of friction between any two surfaces in contact is defined as the ratio of the force of limiting friction and normal reaction between them.

• 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.
