Question

state the laws of limiting friction. Define coefficient of limiting friction​

Answer 1

Answer:

The direction of limiting frictional force is always opposite the direction of motion.

Limiting friction acts tangential to the two surfaces in contact.

The magnitude of limiting friction is directly proportional to the normal reaction between the two surfaces.

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.

Answer 2

Answer:

Laws of limitinf friction:

• The direction of limiting frictional force is always opposite the direction of motion.
• Limiting friction acts tangential to the two surfaces in contact.
• The magnitude of limiting friction is directly proportional to the normal reaction between the two surfaces.
