Answer
A-The Max slope angle of non-Cohesive (free-flowing) granular material. It is measured as the angle between Horizontal plane & the cone slope of such material. It represents the steepest slope at which slope at which the material can be filled without sliding or collapsing.
- When bulk cargo like grains is poured like grains or minerals are poured onto a flat horizontal surface, they
naturally form conical pile. The angle that the cone’s surface makes with the horizontal is called angle of Repose.
