The pendulum consists of two slender rods AB and OC which have a mass of 3 kg/m The thin plate has a mass of 12 kg/m2 . Determine the location of the center of mass G of the pendulum, then calculate the mass moment of inertia of the pendulum about an axis perpendicular to the page and passing through G.

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.

Afluid flows with a velocity field given by v=(x/t)i.. determine the local and convective accelerations when x=3 and t=1.
