Question

A consolidated-drained triaxial test is carried out on a sand
specimen that is subjected to 100 kN/m2 confining pressure.
The vertical deviator stress was increased slowly such that
there is no build-up of pore water pressure within the specimen.
The specimen failed when the additional axial stress
reached 260 kN/m2.
a. Find the friction angle of the sand.
b. Another identical sand specimen is subjected to
200 kN/m2 confining pressure. What would be the deviator
stress at failure?
