Question
Structural Engineering Question on Working stress and Limit state design concepts
A drained triaxial test was conducted on a saturated sand specimen using a stress-path triaxial testing system. The specimen failed when the axial stress reached a value of 100 kN/m2 from an initial confining pressure of 300 kN/m2.
The angle of shearing plane (in degrees) with respect to horizontal is _______ (rounded off to the nearest integer).
Answer
The correct answer is 30.
