A tensile test uses a test specimen that has a gage length of 50 mm and an area = 217 mm2. During the test, the specimen yields under a load of 96,198 N. The corresponding gage length = 50.2 mm - this is at the 0.2% yield point. The maximum load of 160,292 N is reached at a gage length = 64 mm and the specimen fractures at a gage length of 69 mm. Determine the modulus of elasticity in MPa.

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?
