Measured deformation and load at the time of failure are given as 4 mm and 184 N, respectively. Find the undrained shear strength of this soil sample. b) Also, an unconsolidated undrained (UU) triaxial test is performed on the same specimen under o3=100 kPa. Draw the total stress-based Mohr circles for both tests and plot the Mohr- Coulomb failure envelope.

A direct shear test is performed on a soil sample with two different loads. In the first test, a normal stress of 55kPa is applied and the soil fails at a shear stress of 35kPa. In the second test, the soil failed at shear stress of 47kPa when a normal stress of 75 kPa was applied. Determine the values of internal friction angle and cohesion of the given soil sample.
Two different soil samples were subjected to the shear strength test, of which, the first cohesive soil specimen failed at the deviator test of 500 kN/m2, when the cell pressure of 400 kN/m2 was recorded in the tri-axial shear apparatus. The second soil sample with the coefficient of internal friction 30° was subjected to direct shear test.
