If the "B" end were driven by an electric motor and the "A" end were disconnected from the line terminals of the motor controller, the unit illustrated could then be used as a __________. See illustration GS-0057.
• How a hydraulic pump and motor (A-end and B-end) can transmit power in either direction • What changes when you reverse which end is being driven (mechanically vs hydraulically) • Which listed options actually use hydraulic power as the main energy transfer method
• If the B-end is now driven by an electric motor, what form of power does it send through the high‑pressure lines to the A-end? • Looking at the sketch, does the A-end appear to drive an electrical device, a drum, or a hydraulic system when it turns? • Among the choices, which device most logically matches a hydraulic transmission made of a pump and motor connected by high‑pressure lines?
• Identify which answers obviously rely on electrical output (alternator) rather than hydraulic output • Decide which option would reasonably be powered by a hydraulic pressure supply on a ship • Confirm that the function you choose matches a system where the primary energy transfer medium is high‑pressure fluid between A-end and B-end
