The two torsion members of Problem 6.52 (Figure P6.52) are subjected to equal twisting moments. Compare the shear stresses in the members.

Problem P6.52

The hollow circular and square thin-wall torsion members in Figure P6.52 have identical values for b and t. Neglecting the stress concentrations at the comers of the square, determine the ratio of the torques and unit angle of twists for the two torsion members, for equal shear stresses in each.
