A sample of dry sand was placed in a direct shear testing apparatus and was tested until the sample sheared. The normal stress was 96 kN/sq m. The shear stress at failure is provided below (based on the first letter of your last name). If you need it, the sand sample area is 0.0025 sq. meters. Determine the sand's angle of internal friction. SHOW ALL CALCULATIONS. 70 Shear Stress at Failure (kN/sq m)
