SIT S. The results of two-drained tri-axial tests on a saturated clay are recorded as follows:
Specimen A:
Chamber-confining pressure = 104 kPa
Deviator stress at failure = 201 kPa
Specimen B:
Chamber-confining pressure = 170 kPa
Deviator stress at failure = 324 kPa
a. Compute the angle of friction.
b. Compute the cohesion of soil.
c. If the clay specimen above is tested in a tri-axial apparatus with a chamber-
confining pressure of 248 kPa, compute the major principal stress at failure.
