A steel torsion member has a length of 3.00 m and diameter of 120 mm (E = 200 GPa and G = 77.5 GPa). It is fixed to a rigid wall at one end. A steel beam of rectangular cross section, 120 mm by 30.0 mm, is welded perpendicularly to the torsion member at its midsection (Figure P5.96). The beam is supported by a roller located 2.00 mm from the welded section. The free end of the member is subjected to a torque T = 16.0 kN • m. Determine the reaction at the roller.
