Two pieces of high-density polyethylene tubing are fitted together and firmly clamped at their ends. A load of 183 N is applied to the fitting. Tube (1) is 145 mm long, and tube (2) is 105 mm long. Both tubes have an outsider diameter of 23.0 mm and an inside diameter of 17.4 mm. Determine the load carried by tube (2).
