A sand is hydrostatically consolidated in a triaxial test apparatus to 450 kPa and then sheared with the drainage valves open. At failure, (σ1 - σ3) is 1121 kPa. Determine the major and minor principal stresses at failure and the angle of shearing resistance. Plot the Mohr diagram. (This problem should be followed by the next one.)?
