A 2 stroke, 4 cylinder, compression ignition engine having a total displacement volume of 300 in3 and a mechanical efficiency of 85% generates 110 hp at the drive shaft while running at 2100 RPM. Air flows into the engine at a rate of 8.0 lbm per minute. The engine's fuel-to-air ratio is 0.075. A) How much torque is developed

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

Shafts are machine elements that are used to a) carry axial loads b) direct shear loads c) transmit power d) rotate at constant speed e) none of the above circular and square shafts subjected to the same torque under the same circum behave a) the same way b) almost the same way

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