Which component is used to convert compressed air into linear motion?

• A. Cylinder
• B. Valve
• C. Regulator
• D. Filter

Answer: (A)

The component that converts compressed air into linear motion is the pneumatic cylinder. It acts as an actuator with a piston inside a cylinder; when compressed air is admitted to one side of the piston, it pushes the piston forward, causing the rod to extend in a straight line. By routing air to the other side, the piston retracts, pulling the rod back, so the cylinder can provide controlled forward and backward linear movement. The amount of force it can produce depends on the air pressure and the piston’s cross-sectional area (force ≈ pressure × area). Other parts like a valve, regulator, and filter play essential roles but don’t directly create linear motion. A valve directs and controls airflow to the cylinder, a regulator lowers or stabilizes pressure to safe working levels, and a filter cleans incoming air. They support the system, but the cylinder is the element that actually turns compressed air into linear motion.
