Question

Relation between angle of repose and coefficient of friction

Answer 1

Answer:

Where mu = coefficient of limiting friction. This is equal to the tangent of the angle of repose between two surfaces in contact. i.e coefficient of limiting friction between any two surfaces in contact is equal to tangent of the angle of friction between them. i.e angle of friction is equal to angle of repose.

Explanation:

Now, the coefficient of friction is a property of materials, and does not change with the angle - but it is the case that the friction force will decrease since it is Fk=μkFn.

Answer 2

Explanation:

Where mu = coefficient of limiting friction. This is equal to the tangent of the angle of repose between two surfaces in contact. i.e coefficient of limiting friction between any two surfaces in contact is equal to tangent of the angle of friction between them. i.e angle of friction is equal to angle of repose.
