In cars, a gear train (shown in the figure) is used in the transmission to allow the wheels of the car to rotate at high angular speeds while at low engine rpm's, allowing for less gas to be used. If the drive gear in a gear train is connected directly the engine, and the driven gear directly to the wheels (meaning both rotate with their respective gears), how much torque would be delivered to the wheels when the torque produced by the engine is 100 Nm and the drive gear is 3 times larger than the driven gear?
