Angle of Repose

The angle of repose or critical angle of repose of a granular material is the steepest angle of descent or dip relative to the horizontal plane to which a material can be piled without slumping At this angle the material on the slope face is on the verge of sliding Angle of repose - angle where materials will slide out of the tipped body...
