---- Name: Q1 (12 marks) A thin plate of rhombus shape, as shown in the figure below, is subjected to uniform shear strless To along all ofthe four edges. (al (5 marksl Determine the stress state [~: ;;] expressed in the x-y coordinates, and (b) (7 marks) Let the dashed line OP be where the maximum shear stress ('tmax) is generated by 'to. Use Mohr's circle to determine the angle between line OP and x-axis in degrees (as indicated by e in the figure). Note: e < 90°.
