Question

Limiting friction is also known as
A. maximum value of friction
B. Least value of friction
C. None
D. Both

Answer 1

Hint: A maximum quantity of opposing force is in between two contacts, after that one body begins to move with respect to other on applying an external force is known as limiting force of friction of the reference object.

Complete step by step answer:
First of all let us take a look at what limiting friction is. The maximum friction that can be developed between two static surfaces in contact with each other. Once a force given to the two surfaces exceeds the limiting friction, motion will happen. The limiting friction for two dry surfaces is a product of the normal reaction force and the coefficient of limiting friction. When we walk on the road, when a car moves on a cliff, frictional force applied by upstream water to a swimmer and also friction force on a pen by a page or notebook this force friction is acting. So these all are the examples for this.
As the limiting friction is the maximum value of friction developed, they are also known as the ‘maximum value of friction’.

Therefore the correct answer for this question is option A.

Note:
Frictional force is a force that opposes the relative motion between two objects or materials in a surface. The causes for this opposing force are molecular adhesion, surface roughness, and deformations. Adhesion is defined as the molecular force acting when two materials are brought into close contact with each other. Static friction is frictional force between two or more solid materials that are not in a motion relative to each other.
