Multiple Choice

A hydraulic cylinder is commonly referred to as an ______.

Explanation:
A hydraulic cylinder is an actuator. It converts hydraulic energy (fluid pressure) into linear motion to move a load. The entire device—housing, seals, and internal piston—is designed to produce output movement, so it’s referred to as an actuator. The piston is just the moving part inside the cylinder, not the whole device. A motor would imply rotational motion, which isn’t the typical output of a hydraulic cylinder, and a valve is a control component that regulates fluid flow rather than providing the actual motion. So the best term for the hydraulic cylinder is actuator.
