Problem 1:
A material element in plane stress is subjected to the stresses indicated in Figure 1. Do the following:
a. Determine the stresses acting on an element that is inclined at 45-counterclockwise angle relative to the shown in Figure 2. Show the results on a sketch of a properly oriented element.
b. Determine the principal stresses and show the results on a sketch of a properly oriented element. You must indicate the orientation of this element relative to the original.
c. Determine the maximum in-plane shear stress and show the stress state at that orientation on a sketch of a properly oriented element.
