Question

Maximum value of frictional force is called

Answer 1

Answer:

, the force of friction between two surfaces when the body is in static condition is called static friction and is equal to the applied force. The maximum value of static friction is called limiting friction.

Explanation:

this is the maximum value of frictional force

Answer 2

Limiting friction is referred as the maximum value of frictional force.

Explanation:

• Friction that is generated between two surfaces coming in contact with each other and are in static state is referred as limiting friction.
• It is called the maximum value of friction because as soon as the value of applied force exceeds the value of limiting friction, the body gets in state of motion.
• So, in order to change the state of any object from rest into motion, then the applied force must be greater than the limiting friction value.
• It can be precisely defined as the value of friction just at the point where the body starts sliding.
• Direction of motion is opposite to the direction of frictional force.
• There is a direct proportionality relationship between values of normal force and limiting friction.
• Value of limiting friction is not dependent on area or size of surfaces.
• It depends on nature of material, and the smoothness of the surface.
