🔍 Key Concepts

• Epicyclic gearing involves one or more gears revolving around another gear whose center is fixed • Think about where you’ve seen small gears orbiting a larger central gear (e.g., in automatic transmissions, winches, or reduction gearboxes) • Some terms describe how gears move relative to each other, while others are less standard or more generic names

💭 Think About

• Which option names a gear system where smaller gears rotate around a central gear and the whole set can also rotate as a unit? • Can you recall which gear type is commonly used in automotive automatic transmissions and some marine reduction gears for compact, high-ratio gearing? • Look at each choice and ask: does this term typically refer to gears ‘orbiting’ another gear, or something else?

✅ Before You Answer

• Verify which term is most commonly associated in textbooks with epicyclic or planetary motion of gears • Eliminate any options that are not standard, widely used names for known gear train types • Ask yourself which option you’ve actually seen linked with sun gear, planet gears, and ring gear in diagrams or study materials
