The main propulsion shaft turning gear usually connects to the free end of the high- speed high pressure pinion because the __________.

Correct Answer: Option A — greatest gear ratio between the turning gear motor output and bull gear can be obtained

Connecting the turning gear to the high-speed high-pressure pinion yields the maximum overall gear reduction ratio through the double-reduction gear train, allowing a smaller, lower-torque electric motor to effectively rotate the massive main bull gear and propeller shaft.
