10. A saturated sand specimen was used in a consolidated-undrained triaxial test under a consolidation confining pressure of 150kN/m². After completion of the consolidation, the shearing stage started by increasing the axial stress while drainage was prevented. The specimen failed at deviator stress of 200kN/m² with a recorded pore water pressure of 100kN/m². a. Draw the effective and total stress failure envelopes. b. Determine the consolidated-undrained angle of shearing resistance, p. c. Determine the effective friction angle, ø'. (Round all the answers to 2 decimal places. Show all working calculations.)
