a$)$ For the $2-$dimensional cubic element shown above, draw Mohr$$s circle and identify the

location of the Origin of Planes on Mohr$$s circle.

b$)$ What is the Major Principal Stress, $$ and the Minor Principal Stress, $$ What is the

Maximum Shear Stress acting on any plane, $$max$?$

c$)$ What is the orientation $($p$,$ and $$p$)$ of the Major Principal Plane. Draw a properly oriented

Principal cubic element. Include the correct stresses.
