Q1.58 Samples of damp sand are tested in direct shear in which the procedure involves two separate tests, with different normal loads for each test. In test one, using a normal loading a compressive stress equal to 50 kPa is applied and the sample is failed at a shear stress equal to 33 kPa. For test two, the normal stress is 80 kPa and the sample shears at a stress of 51 kPa. Determine the angle of internal friction and the value of apparent cohesion for this sand.
