Question

ist law of limiting friction???​

Answer 1

The first law of limiting friction states that ;

The direction of limiting force is always opposite to the motion of the body!

The magnitude of limiting friction always have a constant ratio with a normal reaction force which acts 2 surfaces internally.

also, it does no depend of rugh surfaces

Answer 2

Answer:

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.
