An angle of repose is the maximum angle from the horizontal that a pile of granular material can have and still be stable. This can apply to a granular material, such as sand, poured on a level surface. The sand will form a cone. The angle of repose is the angle of the side of the cone of sand from the base.
The angle of repose for any particular material is related to the density, surface area and shapes of the particles, and the coefficient of friction of the material. A material with a larger angel of repose will form a steeper pile.
Angle of repose is used to:
