In a hydraulic system, which component is responsible for converting hydraulic energy into linear motion?

• A. Pump
• B. Actuator
• C. Reservoir
• D. Filter

Answer: (B)

Converting hydraulic energy into linear motion is done by the actuator, typically a hydraulic cylinder. When high-pressure fluid is directed into the cylinder, it pushes the piston, producing a straight-line (linear) movement of the piston rod. The force generated follows F = P × A, with P as the hydraulic pressure and A as the piston area, and the speed depends on the fluid flow rate. Other parts set up and maintain the system—the pump provides the energy by creating pressure and flow, the reservoir stores fluid, and the filter keeps the fluid clean—but the actual conversion to linear motion happens in the actuator. (Note: a hydraulic motor would convert energy to rotational motion instead.)
