Which outcome occurs when spool valves within a hydraulic actuator experience aeration?

💡 Explanation

Erratic motion occurs due to cavitation; vapor bubbles forming within the valve collapse and generate pressure waves as fluid accelerates. Because these bubbles form pockets causing inconsistent power transfer, therefore, the controlled motion becomes jerky rather than being smooth and predictable.
