Can the tiny fast output start the same heavy crate as the big slow output?
Show of hands — before you project anything
Why must a 6-tooth output loop three times when an 18-tooth driver turns once?
- A Way more than you'd guess
- B About what you'd guess
- C Way less than you'd guess

- Why must a 6-tooth output loop three times when an 18-tooth driver turns once?
- Why would showing a force meter before the prediction make the load test weaker learning?
- Which real losses make an actual gear train differ from the ideal model?
Where it shows up in real life
- A bicycle shifting between different sprocket sizes
- Clock hands driven at different turning rates by a gear train
- A hand drill or egg beater whose crank turns a smaller gear
