Given two surfaces, the angle of repose between the two surfaces is defined as the angle 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:
where is the limiting coefficient of static friction.
It is numerically equal to the angle of friction.
