A short column is composed of two steel [E = 31,000 ksi, ν = 0.29] segments, each with a length of 4.0 in. Segment (1) is hollow with an outside diameter of 1.10 in. and a wall thickness of 0.16 in.

Two pieces of high-density polyethylene [E = 0.89 GPa] 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).

Axial loads are applied with rigid bearing plates to the solid cylindrical rods. One load of P = 130 kN is applied to the assembly at A, two loads Q = 40 kN are applied at B, and two loads R = 150 kN are applied at C.
