Two pieces of high-density polyethylene [G = 0.75 GPa] tubing are fitted together and firmly clamped at their ends. A torque of 7.7 N·m is applied to the fitting. Tube (1) is 155 mm long, and tube (2) is 105 mm long. Both tubes have an outsider diameter of 21.0 mm and an inside diameter of 16.0 mm. Determine the magnitude of the torque produced in tube (2).
