Question

The compound shaft shown in the figure consists of two steel [ G = 80 GPa ] pipe segments. The shaft is subjected to external torques T B and T C which act in the directions shown. Segment (1) has an outside diameter of 196 mm and a wall thickness of 8 mm. Segment (2) has an outside diameter of 134 mm and a wall thickness of 13 mm. The torque is known to have a magnitude of T C = 26 kN ⋅ m . The shear strain in segment (1) is measured as 495 μrad . Determine the magnitude of external torque T_B .
