An undisturbed soil sample, 100 mm in diameter and 200 mm high was tested in a tri-axial machine. The sample failed at an additional axial load of 3 kN with a vertical deformation of 20 mm. The failure plane was inclined at 50 deg. to the horizontal and the cell pressure was 300 kPa. a.) Determine the angle of internal friction. b.) Determine the deviator stress in kPa. c.)Determine the cohesion of the soil in kPa
