If The Angle Of Friction Is 30 Degree What Is The Coefficient Of Friction Quora from qph.fs.quoracdn.net

Angle of repose is the angle from horizontal at which a material (usually dry) will rest on itself. The angle of repose, or critical angle of repose, of a granular material is the steepest angle of descent or dip relative to the horizontal plane to which a material can be piled without slumping. The angle of repose is the steepest angle of descent or dip of the slope relative to the horizontal plane, when material on the slope face is on the verge of sliding.

Depending on the type and shape of material, frictional forces between the grains might also hold them together.

Angle of repose is defined as the angle of the inclined plane with horizontal such that a body placed on it is just begins to slide. While angel of friction is the angle between the noemal force and athe angel of repose is different from the angel of friction; Stickiness of particles to each other, related to the electrochemical attraction between soil particles. As a result, grains of irregular shape that have the ability to interlock tend to have.
