The displacement volume of an internal combustion engine is 3 liters. the processes within each cylinder of the engine are modeled as an air-standard diesel cycle with a cutoff ratio of 2.5. the state of the air at the beginning of compression is fixed by pı = 95 kpa, t1 = 22°c, and vi = 3.17 liters.

Asimple speed reducer is composed of 2 spur gears. the pinion gear has a pitch diameter of 0.75" and 36 teeth while the driven gear has a pitch diameter of 4.0" and 192 teeth. a)-what is the diametral pitch of each gear? b)-if an electric motor rotating ccw at 3000 rpm is coupled to the pinion, what is the rotational speed of the driven gear? c)-if the torque delivered to the pinion is 1 n-m, what is the torque on the driven gear? d)-what is the power transmitted by the gear train?
