A specimen of saturated soil was in a cell pressure of 100 kN/m². The axial stress was then increased and drainage was prevented. The specimen failed when the axial deviator stress reached 80 kN/m² and pore water pressure 40 kN/m². Determine the consolidated angle of shearing resistance o, and drained friction angle, φ'.
