Consider a micro mirror which is tethered by two torsional springs. Mirror and tethers are made of aluminum. Two tethers are fixed at the end. The length of tether (L) is 5 µm, thickness (t) is 0.3 µm, and width (w) is 1 µm. Assume that aluminum’s Young’s modulus is 70 GPa and Poisson’s ratio is 0.33. The micro mirror tilts into/out of the page with angle of ± 12°. What is the required torque to make the mirror tilted ± 12°?

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.
