Q

Air bubbles in a hydraulic governor can cause __________.

🔍 Key Concepts

• Hydraulic governor operation – how fluid transmits motion and control in a governor system • Effect of air in hydraulic systems – compressibility of air vs. incompressibility of oil • Governor response and stability – what happens when the control medium becomes spongy or elastic

💭 Think About

• Think about whether air bubbles make a hydraulic system react faster, slower, or more erratically compared to solid oil only. • Consider if trapped air would help the governor hold a perfectly constant speed, or make it harder to maintain a steady setpoint. • Ask yourself: does air in the oil make the system more precise and sensitive, or less precise and more cushioned in its response?

✅ Before You Answer

• Verify that hydraulic oil is essentially incompressible while air is highly compressible, and think how that affects motion transmission. • Check which choice describes a behavior you’d expect from a system that feels spongy or springy instead of solid. • Eliminate any option that suggests an improvement in precision or stability, and focus on effects that sound like performance degradation.
