Question

explain why
Angle of friction is equal to angle of repose​

Answer 1

Answer:

This is the correct answer

Answer 2

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 ✌️
