🔍 Key Concepts

• Speed droop: how much the governor speed changes between no‑load and full‑load for a given fuel rack movement • How a lever fulcrum position changes the mechanical ratio between flyweight movement and fuel control movement • Difference between changing spring tension (speed setting) and changing linkage geometry (droop / proportional band)

💭 Think About

• From the illustration, trace what each listed part (compensating lever fulcrum, speed droop lever fulcrum, speeder spring tension) is connected to. Which ones actually change the ratio between speed change and fuel change? • Ask yourself: if you change speeder spring tension only, does the no‑load to full‑load speed difference (droop%) change, or does the whole speed range simply shift up or down together? • Look at how the speed droop lever is labeled and linked. Which adjustment(s) would alter the preset droop without necessarily changing the basic speed set by the governor?

✅ Before You Answer

• Verify which components in the drawing are part of the speed droop lever/adjustment linkage versus the basic speed‑setting (speeder spring) linkage. • Check whether moving a fulcrum in a lever system changes the mechanical advantage, and thus the proportional response (droop) of the governor. • Be sure you can distinguish between an adjustment that sets governor speed setpoint and one that sets governor speed droop (percent change between no‑load and full‑load) before choosing.
