Question

Maximum value of static friction is called
Limiting friction
(b) Rolling friction
(c) Normal reaction
(d) Coefficient of friction​

Answer 1

Answer:

Force of friction always acts at point of contacts of the two surface. As the force causing motion increases the frictional force increases up  to certain maximum value and that maximum value of force of friction is called limiting friction. Hence the given statement is true.

Answer 2

Answer:

Maximum value of static friction is called limiting friction.

Additional Information :

• Limiting friction is the friction on a body just before it starts moving.
• The limiting friction force is always opposite of the motion of the object.
• When the object is on the point of sliding then the limiting friction generate.
• Maximum frictional force = coefficient of friction × the normal reaction force.
• Example of limiting friction : Moving of an object on ground.
