Question

Show the relation between Angle offriction and Angle of Repose. Also explain what

are conservative forces ​

Answer 1

Explanation:

The main difference between angle of friction and angle of repose is that the angle of friction is defined as the angle between the normal reaction force and the resultant force of normal reaction force and friction when an object just begins to move, whereas the angle of repose is defined as the minimum angle of an ...

Angle of repose is defined as the minimum angle made by an inclined plane with the horizontal such that an object placed on the inclined surface just begins to slide.

Relation between Angle of Friction and Angle of Repose

Let us consider a body of mass ‘m’ resting on a plane.

Also, consider when the plane makes ‘θ’ angle with the horizontal, the body just begins to move.

Let ‘R’ be the normal reaction of the body and ‘F’ be the frictional force.

Here,

mgsinθ = -F ——> (i)

mgcosθ = -R ——>(ii)

Dividing equation (i) by (ii)

Or, Tanθ = µ, where ‘µ’ is the coefficient of friction

Or, Tanθ = Tanɑ (tanɑ = µ)

where ‘ɑ’ is the angle of friction

θ = ɑ

Angle of repose is equal to angle of friction.

Answer 2

Answer:

The main difference between angle of friction and angle of repose is that the angle of friction is defined as the angle between the normal reaction force and the resultant force of normal reaction force and friction when an object just begins to move, whereas the angle of repose is defined as the minimum angle of an
