A cohesive soil specimen has a shearing resistance equal to 28° and a cohesion of 31. If the max. shearing stress of the soil sample is equal to 65 kPa. Compute the lateral pressure in the cell for a failure. (2 Compute the max. principal stress to cause failure. 3 Compute the normal stress at the point of max. shear.
