Solve: Determine the force P that must be applied to cylinder

2.19      The brass tube AB (E = 15 x10⁶) has a cross-sectional area of 0,22 in² and is fitted with a plug at A. The tube is attached at B to rigrid plate which is itself attached at C to the bottom of an aluminium cylinder E = 104 x 10⁶psi with a cross-sectional area 0,40 in². The cylinder is then hung from a support at D. In order to close the cylinder, the plug must move down through 3/64 in. Determine the force P that must be applied to cylinder.
