A cylindrical sample of cohesive soil tested in the unconfined compression test. At failure, the unconfined compressive stress is 80 kPa and the failure plane makes an angle of 50' with the horizontal: 1) Calculate the angle of internal friction. 2) Calculate the value of cohesion. 3) Is the sample is saturated or not?
