Question

Limiting force of friction is the

• A. Ratio of limiting friction and normal reaction
• B. Friction force acting when the body is just about to move
• C. Tangent of angle between normal reaction and the resultant of normal reaction and limiting friction
• D. Friction force acting when the body is in motion

Answer 1

Answer:

B. Friction force acting when the body is just about to move

Limiting force of friction is the maximum friction force that acts on a body just before it starts moving. It is independent of the area of contact and proportional to the normal force.
