The minimum requirements for a hydraulic system include a source of power, a means to transmit the power, and a ________?

Explanation:
A hydraulic system needs energy creation, a way to move that energy, and something that actually uses it to do work. The component that uses the energy is the actuator—such as a hydraulic cylinder for linear motion or a hydraulic motor for rotational motion. Without an actuator, the pressurized fluid has no mechanism to convert that energy into useful work. A reservoir stores fluid, which is common but not essential for the basic function; a filter and a gauge serve supportive roles (cleanliness and monitoring) but don’t perform the work. So the device to use the power is the key element.
