Particles dropped in a pile create an angle of repose based on their size and angularity. 2. Fine sand assumes a shallower angle of repose.. 3. Than an • angular pebbled do( fine sand, coarse sand, pebbles) smallest to largest • Angle of repose- the angle for a particular material type at which the material will be...
