Q

Failure of the speeder spring in a mechanical governor will __________.

🔍 Key Concepts

• Mechanical governor basic balance between centrifugal force of the flyweights and the speeder spring force • What happens if the speeder spring force is lost or greatly reduced • How governor movement changes fuel rack position when the balance is disturbed

💭 Think About

• Picture the governor at steady speed: are the flyweights held in by the spring or pushed out by centrifugal force? What keeps them in equilibrium? • If the speeder spring suddenly fails, what happens to the balance of forces on the flyweights, and do they move inward or outward? • When the flyweights move (in or out), does the governor mechanism move the fuel rack toward more fuel or less fuel, and how does that affect engine speed?

✅ Before You Answer

• Be clear on which element (spring or centrifugal force) is trying to increase speed and which is trying to reduce it • Trace the motion: failure of the speeder spring → flyweights move → pilot valve/linkage moves → fuel rack change → speed up or slow down • Eliminate any option that ignores a change in fuel setting, because a governor’s whole purpose is to change fuel to control speed
