Pressure Vessels

The term pressure vessel refers to a closed container that contains gas or liquid at a different pressure than environment pressure. The pressure vessels have a wide scale of applications in our day-to-day lives and other industrial places. Some common examples of pressure vessels are gas cylinders, autoclaves, compressor vessels, etc.

The mechanical assembly shown in the figureconsists of an aluminum tube, a rigid end plate, andtwo steel cables. The slack is removed from the cablesby rotating the turnbuckles until the assembly is snugbut with no initial stresses. Afterward, the turnbucklesare tightened by 1.5 turns. Calculate the forces inthe tube and the cables and determine the shorteningof the tube. As = 0.85in2 for each cable, AA = 4.5 in2,L = 20 in., Es = 29,000 ksi, EA = 10,600 ksi, andp = 1/16 in.
