For angle of friction , we had and we see that this is the same expression that we get for angle of repose as well Therefore, angle of friction is equal to angle of repose In soil mechanics, the angle of repose refers to the shallowest angle of a pile of soil that causes soil particles begin to fall down
The major difference is that angle of friction is defined for rigid bodies while angle of repose is defined for granular particles like sand (Angle of repose)Another minor difference is that angle of repose is a real angle which can be directly measured while angle of friction is a hypothetical angle …
Apr 10, 2010 · On the other hand, if all a person is looking for is a ballpark idea as to what is acceptable, then the 45 degree angle of repose comes into play It is a general rule of thumb that you need to protect the soil below the foundation and out at 45 degrees to each side
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 At this angle, the material on the slope face is on the verge of sliding
