angle of repose

[′aŋ·gəl əv ri′pōz]
(engineering)
(mechanics)
The angle between the horizontal and the plane of contact between two bodies when the upper body is just about to slide over the lower. Also known as angle of friction.

angle of repose

The maximum angle with the horizontal at which a mass of material, as in a cut or embankment, will lie without sliding; the angle between the horizontal and the maximum slope that a soil assumes through natural processes.
