Lower headlight beams must be used when approaching within of an oncoming vehicle or when following within of the rear of another vehicle.

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.

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.

For a gate width of 2 m into the paper, determine the force required to hold the gate abc at its location.
