[edit] Food engineering

Angle of repose has great importance in food engineering, especially that deals with grain material storage and handling in large amounts in chutes.

I hear it may have some significance to archaeology as well: most minor pyramids in Egypt were built at an angle of 43° from the horizontal, which is the angle of repose for sand. Many of those built at the higher angle of 54° ended up collapsing.thefamouseccles

[edit] Formula for spheres

Is there a formula relating the angle of repose to the coefficient of friction for homogeneuous spheres? I recall seeing such a formula, but cannot find it now.
