1. Identify critical points and determine the stress elements. 2. Apply stress transformation theory to solve for the principle stresses at the most critical point(s) identified. Use either the numerical method or graphical method (Mohr's circle). Show the principal stress element(s). 3. Repeat item 2 by using Matlab and show the changes of stress condition on the faces of the element as it is rotated. 4. Use Failure Theories to determine safety of the product and interpret the result by providing a conclusion.
