How to Calculate the Angle of Repose | Sciencing

The angle of repose is the minimum angle at which any piled-up bulky or loose material will stand without falling downhill. One way to demonstrate this would be to pour sand from a bag to the ground. There is a minimum angle or maximum slope the sand will maintain due to the forces of gravity and the effect of friction between the particles of sand. The angle is calculated between the peak of ...
