When the outside temperature is 5.2 ⁰c, a steel beam of cross-sectional area 52 cm2 is installed in a building with the ends of the beam bolted securely to two immovable pillars. in the summer thetemperature of the beam rises to 37⁰c. what is the compressional force fn on the beam? the coefficient of linear expansion of steel 1.1 × 10−5? c−1 and young’s modulus of steel is 2 × 1011 n/m2. answer in units of n.

Steam at a pressure of 100 kpa and a quality of 50% initially fills a rigid vessel having a volume of 0.5 m^3. the steam is then heated, causing the pressure in the vessel to rise to 150 kpa. determine: i. the mass of the steam in the vessel. ii. the temperature and quality of the steam after the heating process. ii the mass of the vapour, mg and liquid, m in the vessel after the heating process. if the steam in the vessel is now further heated, what would the pressure and temperature in the vessel be when all steam has turned into saturated vapour? b. sketch the processes in part (a) and part (b) on p-v and t-v diagrams, indicating clearly the temperatures, pressures and the paths. c.
