The relationship between the relative density, Dr, and the angle of friction, phi prime, of a sand can be given as phi prime=25 + 0.18Dr (Dr in percent). A drained triaxial test on the same sand was conducted with a chamber confining pressure of 124 kN/m^2. The relative density of compaction was 60%. Calculate the major principal stress at failure.
