Angle of Repose of Snow on Solids

ROBERT SCHNURMANN

Top

IT is well known that the friction of solids on snow surfaces is larger than on ice surfaces. The higher kinetic friction obtained on snow is attributed to the extra work done in displacing and compressing the snow crystals1. This may apply to the sliding of a ski or a sleigh on snow. It is, however, common experience that snow also while resting, for example, on the roof of a house or on a metal spade, exhibits a considerable angle of repose.
