Q1. The stresses acting on a soil element are shown in Figure 1. Draw the Mohr's circle and determine graphically: a). the magnitude of the major and the minor principal stresses and the orientation of the two principal planes. b). the normal stress, and the shear stress, Ta on the a-plane. c). Describe the steps in the graphical solution for a) and b). 67 40 kPa 50 kPa a-plane 73 40 25 kPa 100 kPa Figure 1 Q1. The stresses acting on a soil element are shown in Figure 1.
