Q

Which is TRUE for the directive force acting on a gyrocompass?

🔍 Key Concepts

• Relationship between Earth’s rotation, latitude, and gyrocompass directive force • Difference between true equator/poles and magnetic equator/poles • How the horizontal component of the Earth’s rotation vector changes with latitude

💭 Think About

• Think about how the Earth’s rotation axis is oriented relative to the gyro when you are at the equator versus at the poles. • Ask yourself: at which latitude does the Earth’s rotation create the strongest horizontal effect that tries to align the gyro’s spin axis to true north-south? • Consider whether a gyrocompass cares about the magnetic field at all, or only about the Earth’s rotation and gravity.

✅ Before You Answer

• Verify whether gyrocompass directive force is related to the Earth’s magnetic field or to its rotation. • Visualize the horizontal component of the Earth’s rotation vector: is it largest at the poles or at the equator? • Be sure you are distinguishing between geographic equator/poles and the magnetic equator/poles named in one of the options.
