A soil has unconfined compressive strength of 120 kN/m2. In a triaxial compression test, a specimen of the same soil when subjected to a chamber pressure of 40 kN/m2 failed at an additional stress of 160 kN/m2. Determine: a) The cohesion of the soil in kPa b) The angle made by the failure plane with the axial stress in the triaxial test c) the angle of internal friction
