The beam AB is supported by a single-shear pin connection at joint A and by a double-shear connection to member (1) at joint B. Member (1) is connected to the support at C with a double-shear pin connection. Member (1) has a cross-sectional area of 100 mm2 and a yield strength of 340 MPa. The pins at A, B, and C each have a diameter of 12 mm. and an ultimate shear strength of 270 MPa. Specifications call for a minimum factor of safety in member (1) of 1.67 with respect to its yield strength. The minimum factor of safety required for pins A, B, and C is 2.5 with respect to the pin ultimate shear strength. Determine the max. allowable distributed load w, in kN/m, that may be applied to the beam AB. Use dimensions of a

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.
