Problem 3:
find the amount of power that is delivered to a load at 1 = 3ms if the current entering the
positive terminal is given by the following expression for current:
i=5cos60pit
with voltages given by the expression (a) v = 3i and (b) v = 3di/dt

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?
