Athree-point bending test is performed on a glass specimen having a rectangular cross section of height d=5mm and width b=10mm; the distance between support points is 45mm.
a) compute the flexural strength of the load at fracture is 290n.
b) the point at maximum deflection delta(y) occurs at the center of the specimen and is described delta(y)=fl^3/48ei, where e is the modulus of elasticity and i is the cross-sectional moment of inertia. compute delta(y) at a load of 266n.

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.
