Which impairment reduces power when a hydraulic actuator rapidly cycles?

💡 Explanation

Cavitation causes surface damage via imploding vapor bubbles. Therefore, pump efficiency decreases because metal erodes due to repeated implosions; rather than momentary issues from viscosity, valve stiction, or creep which causes constant rather than intermittent output impairment.
