Question
1. At a point , the major principal stress 66 KPa (c) and the minor principal stress is 34 KPa (T). a) Use Mohr's circle to determine shear and normal stress acting 45 degrees counterclockwise (CCW) from major principal plane, b) Determine the stress combination 75 degrees CCW from major principal plane. 2. The normal and shear stresses on a plane are 120 psi (C) and 25 psi respectively. On an orthogonal plane, the respective stresses are 40 psi (C) and 25 psi. Draw Mohr's circle and determine the angle between minor principal plane makes with the 120 psi stresses. 3. For a normally consolidated clay, the following were recorded; confining pressure= 03 = 140KPA and Aod = 264 KPa. Find ø. 4. For a normally consolidated clay, Ø=26 degrees in the C-D test. The soil fails at deviator stress of 23 psi. What is the chamber pressure.
