Choose the correct statement about the basic method for constructing an influence line. according to the basic method, the influence line can be constructed by placing the unit load at a variable position x on the member and then calculating the value of the function (reaction, shear, or moment) at the point as a function of x. according to the basic method, the influence line for a loading (reaction, shear, or moment) is to the same scale as the deflected shape of the beam when the beam is acted upon by the loading. to draw this deflected shape, the capacity of the beam to resist the applied loading must be removed so the beam can deflect when the loading is applied.

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?

The catalogue for a refrigerant 22, four-cylinder, hermetic compressor operating at 29 r/s. a condensing temperature of 40°c and an evaporating temperature of -4°c shows a refrigeration capacity of 115 kw. at this operating point, the motor (its efficiency is 90 percent) draws 34.5 kw. the bore of the cylinders is 87 mm and the piston stroke is 70 mm. the performance data are based on 8°c of sub-cooling of the liquid leaving the condenser. compute (a) the actual volumetric efficiency and (b) the compression efficiency.
