Discussion
The function of which of the following hydraulic device is analogous to that of the flywheel of a reciprocating engine and an electric storage battery?
Answer: B
The device is the hydraulic accumulator.
An accumulator stores hydraulic energy, usually as pressurised liquid under a weighted or gas-charged ram, when demand is low, and releases it when machines such as presses or lifts need more than the pump can supply. A flywheel stores energy mechanically in the same way and an electric battery stores it electrically, which is the analogy the question draws.
A hydraulic ram lifts water using the momentum of a flow, an intensifier raises the pressure of a supply, and a jack multiplies force to lift loads. None of them stores and releases energy.
