Hey guys, I would just like some confirmation that I got this question correct.
For the stress block shown in Figure 3a, using the stress equations;
a) Calculate the stresses sigmax' sigmay' and taux'y' on a stress block rotated 15° clockwise from the x-y axes.
b)Calculate the principal (normal) stresses and the principal in-plane shear stress (and
corresponding normal stresses) and their orientation (rotation angle). Sketch both these situations
on stress blocks. Assume plane stress conditions.
