A structural steel beam is loaded in such a way that a stress block is subjected to the stresses shown in Figure 2. Solve the problem using Mohr's circle drawn on a piece of graph paper with coordinates for all relevant points.

a. Determine the in-plane principal stresses and the angle of orientation. Show your results on a stress block.

b. Determine the maximum in-plane shear stress, the normal stresses, and the angle of orientation. Show your results on a stress block.
