At the end of the CD triaxial pressure experiment on a normal consolidated clay, the sample was defeated along a plane of 570. When another sample with the same properties was tested in the CU experiment, the pore pressure in the defeat was measured as 85 kPa. According to the cell pressures (63) 200 kPa in both experiments; a) At the end of the A = CD experiment, find the effective internal friction angle and the difference in prime stress. b) At the end of B = CU experiment, find the total angle of internal friction and angle of defeat plane. c) In the C = CU test, find the shear strength in the plane of failure.
