Question

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

Answer 1

Frictional forces act at the point of contact of two surfaces.the force which causes the motion of the body results in the increase in the frictional forces up to a certain maximum value. This maximum value of the force of friction is called the limiting friction. For a body to move the applied force must be greater than the limiting friction.

Complete answer:
Friction is the force that resists the relative motion of any solid surfaces, fluid layers, and material elements sliding against each other.
We know that Static friction is defined as the friction acting between two or more solid objects that are not moving relative to each other. For example, it prevents an object from sliding down a sloped surface. It is considered to arise as a result of surface roughness features across multiple length-scales at solid surfaces static friction force that need to be overcome by an applied force to make an object move.
One of the examples of static friction is that it prevents a car wheel from slipping as it rolls on the ground. When the wheel is in motion, the area of the tire in contact with the ground which is found to be stationary for the ground, so we can say that its static friction than kinetic.
For a body to be in motion, it needs to overcome the force of friction which applies in opposite to the force of the body to be in motion. The maximum value of static friction which is generated between two surfaces is known as the limiting friction.

$\therefore$ The maximum value of the static friction is called limiting friction. Option (A) “True” is the correct option.

Additional information:
Some of the common uses of friction are below.
(i) It is used to in ignition of a matchstick by producing heat (friction arising between the head of a matchstick and the surface of the matchbox while rubbing)
(ii) It is used to prevent objects from slipping off from a smooth surface with the help of sticky pads (Sticky pads effectively increases the friction coefficient between the surface and the object.

Note:
Do not get confused with the terms, force of friction and the force required to hold the body in the motion.
For a body, friction is the force that exists between the two-layers of the surface.
