An undeformed specimen of some alloy has an average grain diameter of 0.050 mm. you are asked to reduce its average grain diameter to 0.020 mm. is this possible? if so, explain the procedures you would use and name the processes involved. if it is not possible, explain why?

What precautions should you take to prevent injuries when dealing with heavy loads?

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false
