Question

The magnitude of the limiting friction between two surfaces is independent of the ___________and shape of the surfaces in contact.



​

Answer 1

Answer:

Area

Explanation:

As long as the normal reaction remains the same, the magnitude of limiting friction is independent of the area, and the shape of surfaces that are in contact. The magnitude of the limiting friction F is directly proportional to the normal reaction R between the two surfaces which are in contact.

Answer 2

Answer:

• As long as the normal reaction remains the same, the magnitude of limiting friction is independent of the area, and the shape of surfaces that are in contact.

• The magnitude of the limiting friction F is directly proportional to the normal reaction R between the two surfaces which are in contact.
