🔍 Key Concepts

• Basic parts of a gyrocompass (what the rotor is vs what the support/frame is) • What provides damping and stability to the gyro (especially in older liquid or mercury systems) • The role of liquid-filled reservoirs and tubes in correcting and stabilizing the compass

💭 Think About

• Which option best describes something that would logically involve reservoirs and connecting tubes rather than a solid spinning part? • Think about which terms sound like mechanical support parts versus liquid/ballistic systems in a gyrocompass. • Eliminate any answers that clearly refer to the spinning mass itself or to unrelated electronic devices.

✅ Before You Answer

• Identify which choice refers to the spinning element of the gyro (this is NOT the system of reservoirs and tubes). • Identify which choice names a frame/support structure (this is also NOT the system of reservoirs and tubes). • Focus on the term that suggests a liquid-based ballistic/damping system used to stabilize the gyrocompass.
