🔍 Key Concepts

• Relationship between governor speed range and spring characteristics • How spring stiffness and geometry affect sensitivity and stable control over varying speeds • Which spring shapes maintain a more linear or controllable force–deflection behavior over a wide range of compression

💭 Think About

• Think about what a governor must do differently when the engine runs at both very low and very high speeds. • Which spring shape keeps its controlling force predictable and smooth as it is compressed or extended over a large distance? • Consider which spring design is commonly used where precise, stable speed control over a broad range is important.

✅ Before You Answer

• Compare how force vs. deflection behaves for each spring type listed. • Ask which spring form is typically used in speed governors or control mechanisms rather than for simple, small-range adjustments. • Verify which design best maintains sensitivity and stability when the operating speed changes significantly.
