The solid aluminum shaft has a diameter of 50 mm and an allowable shear stress of 60MPa. Determine the largest torque T1 that can be applied to the shaft if it is also subjected to other torsional loadings.Also, determine the maximum shear stress within regions CD and DE. I do not have access to G and E for aluminum, so for now, assume G =28 GPa and E = 69 GPa.

Please show all your work.
