A circular tube of outer diameter d3= 70 mm and inner diameter d2= 60 mm is welded at the right-hand end to a fixed plate and at the left-hand end to a rigid end plate (see figure). A solid, circular bar with a diameter of d1= 40 mm is inside of, and concentric with, the tube. The bar passes through a hole in the fixed plate and is welded to the rigid end plate. The bar is 1.0 m long and the tube is half as long as the bar. A torque T = 1000 N · m acts at end A of the bar. Also, both the bar and tube arc made of an aluminum alloy with a shear modulus of elasticity G = 27 G Pa.
