The data obtained for a direct shear test are as follows. Normal pressure 20 kN/m2 , tangential pressure = 16 kN/m2 .Angle of internal friction = 20˚, cohesion = 8 kN/m2 . Represent the data by Mohr circle and compute the principal stress and the direction of principal planes. Also draw the failure plane.

A direct shear test is conducted on a large specimen of dry sand (square cross section with following dimensions: 7.5 cm x 7.5 cm x 3.0 cm [height], Mass = 271.0 g) with a normal stress of 500 kPa. Failure occurred when the horizontal force was 1.96 kN. For the same sand, tests were also conducted to determine the specific gravity and the maximum and minimum void ratios. These tests yielded the following results: Gs= 2.65, emax=0.80, emin = 0.45....
