QUESTION 5
10 points
A consolidated-drained (CD) triaxial test is conducted on a specimen of sandy soil, which the cohesion (c') can be assumed to be 0. The total stress confining pressure (i.e. cell pressure) is 418kPa, and back pressure is 320kPa. At failure, the applied vertical force is 790N and the cross-sectional area is 1674mm2. Estimate the friction angle of the sand in degree.
