PROBLEM 2.18 The brass tube AB (E = 15 ? 106 psi) has a cross-sectional area of 0.22 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. In order to close the cylinder, the plug must move down through in. Determine the force P that must be applied to the cylinder.

In a certain experiment, cylindrical samples of diameter 4 cm and length 7 cm are used. The two thermocouples in each sample are placed 3 cm apart. After initial transients, the electric heater is observed to draw 0.6 A at 110 V, and both differential thermometers read a temperature difference of 10°C. Determine the thermal conductivity of the sample.
