The same sand as in Problem 1 is tested in a direct shear apparatus under a normal pressure of 420 kPa. The sample fails when a shear stress of 280 kPa is reached. Determine the major and minor principal stresses at failure and the angle of internal friction of the soil. Plot the Mohr circle and Mohr-Coulomb failure envelope at the point of failure.
