Info

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 on which the material can be piled without slumping. At this angle, the material on the slope face is on the verge of sliding. The angle of repose can range from 0° to 90°.

Setup Instructions

1. Adjust the angle of a wooden incline until various objects begin to slide.

2. Then substitute the wooden incline with a teflon one.
