🔍 Key Concepts

• Governor control behavior when the load on a prime mover changes • Difference between over-control (too aggressive) and under-control (too weak) response • How a stable speed vs. a continuously varying speed would look in operation

💭 Think About

• Imagine a governor that reacts too strongly to any small speed change: what kind of speed pattern would you see over time? • Compare a one-time temporary speed dip or rise after a load change to a continuous back-and-forth speed fluctuation. Which sounds more like 'hunting'? • Think about whether hunting suggests the governor has too much control power or not enough control power.

✅ Before You Answer

• Identify which choices describe a continuous or repeated speed variation, not a single temporary change • Decide whether over-control vs. under-control is more likely to cause rhythmic oscillations around the desired speed • Check which options are describing a definition of a setting or deadband versus a description of an actual unstable speed behavior
