Explanation:
Coefficient of friction is defined as the ratio of the force required to move tow sliding surfaces over each other, and the force holding them together [18].
Static friction is the type of friction that exists when two objects touch each other at rest. It has a limiting value called limiting friction, which is equal to the least force required to move the body from rest. When the external force F is increased, a stage comes when the body is just to start motion
