When one body tries to move to another body, in response to the applied force, an opposing force called frictional force is produced and works in the opposite direction. Static friction is the type of friction that exists when two objects touch each other in the event of a break. It has a limiting value called Limiting Friction which is the minimum required to move the body from the position of rest. It is equal to a lower force. When the external force F increases, the level comes when the body is just on the verge of moving, at this stage, the force of friction is at its maximum, the limiting house. The amount of corrosion depends on the nature and condition of the polished surface of the two exposed surfaces. As long as the normal reaction remains the same, the amount of friction is independent of the area and size of the exposed surfaces. Friction 'F' Is directly proportional to the normal reaction 'R' between the two surfaces in contact.
