Question

The maximum value of static friction is called limiting friction.
A. True
B. False
C. Ambiguous
D. Data insufficient

Answer 1

Hint: Friction may be a force between two surfaces that are sliding, or trying to slip, across one another. For instance, once you attempt to push a book along the ground, friction makes this difficult. Friction always works within the direction opposite to the direction during which the thing is moving, or trying to maneuver.

Complete step by step answer:
Force of friction always acts at the point of contact of the $2$ surfaces. because the force causing motion increases the frictional force increases up to a certain maximum value which maximum value of force of friction is named limiting friction. Hence the given statement is true. As for an example if someone tries to push a block then if he exerts the force greater than the limiting friction then only he can push the box.

So, the correct answer is “Option A”.

Additional Information: The maximum friction which will be generated between two static surfaces in touch with one another. Once a force applied to the two surfaces exceeds the limiting friction, motion will occur. for $2$ dry surfaces, the limiting friction may be a product of the traditional reaction force and therefore the coefficient of limiting friction.

Note: Static friction may be a self-adjusting force because it comes into play when the body is lying over the surface of another body with none motion. If we've not applied any force on a body to maneuver the body, the frictional force also becomes zero. If we start applying force, with the applied force, the frictional force also starts increasing. This happens until the applied force is a smaller amount than limiting frictional force.
When that body overcomes the force of static friction, the utmost value of static friction is reached -which is understood as limiting friction. After the limiting friction, the frictional force isn't getting to increase further. At this stage, the thing moves overcoming the frictional force which is at a continuing value. This is often called kinetic friction.
