Explain the relationship between the angle of repose of a material and its optimal stockpiling strategy using a loader.

The angle of repose of a material is the steepest angle at which a pile of that material will remain stable without slumping or collapsing. It's determined by the material's friction, cohesion, shape, and moisture content. Understanding a material's angle of repose is crucial for developing an optimal stockpiling strategy using a loader because it dictates the shape and stability of the stockpile. Materials with a low angle of repose, such as dry sand or gravel, will form flatter, wider stockpiles. Materials with a high angle of repose, such as crushed stone or damp clay, will form steeper, taller stockpiles. When stockpiling with a loader, the objective is to maximize the stockpile's volume while maintaining its stabi....
