WebThe 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 on which the material can be piled without slumping. At this angle, the material on the slope face is on the verge of sliding. The angle of repose can range from 0° to 90°. The morphology of the material affects the angle of … WebUsing Meyerhof's General Bearing Capacity Equation, calculate the Net Allowable Bearing Capacity of the footing shown with the following data: For SOIL, Cohesion, c = 19 kPa The angle of internal friction =23 Unit weight of moist soil, y = 19 kN/m3 Unit weight of submerged soil, ysub= 11 kN/m3 For footing, X=4.2m Y=3.5m Df=3.2m Use a Factor of …
