Revisit the torsion analysis done in class that compared a solid round, a rectangular and an elliptical cross section. The circle will be the baseline and all other shapes must have the same area as the circle. Assume the shear stress for a circle has a value t = 18 ksi. For an aspect ratio of both the ellipse and rectangle of 8, calculate the shear stress t for the: a.) ellipse b.) rectangle
