A cylindrical specimen of some metal alloy 11.4 mm (0.4488 in.) in diameter is stressed elastically in tension. A force of 14700 N (3305 lbf) produces a reduction in specimen diameter of 6 × 10-3 mm (2.362 × 10-4 in.). Compute Poisson's ratio for this material if its elastic modulus is 100 GPa (14.5 × 106 psi).

Asteam is contained in a rigid tank with a volume of 1 m3. initially, the pressure and temperature are 7 bar and 500 oc, respectively. the temperature drops due to cooling process. determine: (1) the temperature at which condensation begins in °c, (2) the fraction of the total mass that has condensed when the pressure decreased to 0.5 bar. (3) the volume in m3 occupied by saturated liquid at the final state?
