Definition

Given two surfaces, the angle of repose between the two surfaces is defined as the angle \theta that a fixed inclined plane made up of one surface must make with the horizontal so that a body with the second surfaces placed on it just starts slipping.

This angle is numerically given by:

\! \theta = \tan^{-1}(\mu_s)

where \mu_s is the limiting coefficient of static friction.

It is numerically equal to the angle of friction.
