A steel column with an outer diameter of 50 mm and an inner diameter of 40 mm surrounds a solid steel bar with a diameter of 30 mm. A support at one end of the bar and a hard plate at the other end of the tube hold them both tightly in place. A torque T = 650 Nm acting on the end plate twists the composite bar, which has a height of 850 mm. Assuming that the steel's shear modulus is G = 80 GPa, find the maximum shear stresses in the bar and tube, respectively, and the angle of rotation (in degrees) of the end plate
