Q: A consolidated-drained tri-axial test was conducted on a normally consolidated clay. The results are as following: confining stress, G3 = 150 kN/m² and deviator stress, (Aod)t = 150 kN/m². i) Determine angle of friction, p; ii) Determine angle 9 that the failure plane makes with the major principal plane; iii) Find the normal stress and the shear stress ty on the failure plane; and iv) Determine the effective normal stress on the plane of maximum shear stress. Express your results in two decimal places.

Question
Q: A consolidated-drained tri-axial test was conducted on a normally consolidated clay. The
results are as following: confining stress, G3 = 150 kN/m² and deviator stress, (Aod)t = 150
kN/m². i) Determine angle of friction, q; ii) Determine angle 0 that the failure plane makes
with the major principal plane; iii) Find the normal stress and the shear stress ty on the failure
plane; and iv) Determine the effective normal stress on the plane of maximum shear stress.
Express your results in two decimal places.
