The following shaft consists of a 3.50 m long steel shaft and a 2.00 m long aluminum tube. The steel and aluminum are rigidly bonded together in the first 2.00 m. The applied torque T is 50 kN-m. The data is listed in the table.

Determine:

1. The maximum shear stress in the aluminum (composite section).
2. The maximum shear stress in the steel (composite section).
3. The maximum stress in the steel.
4. The total deformation of the shaft at the free end.
