The brass tube AB (E = 15 × 106 psi) has a cross-sectional area of 0.26 in2 and is fitted with a plug at A. The tube is attached at B to a rigid plate that is itself attached at C to the bottom of an aluminum cylinder (E = 10.4 × 106 psi) with a cross-sectional area of 0.40 in2. The cylinder is then hung from a support at D. To close the cylinder, the plug must move down through 364 in. Determine the force P that must be applied to the cylinder. The force P that must be applied to the cylinder is kips.
