HINT HINT HINT HINT!
HERE ARE SOME HINTS!
- Gear Train One is four sets of 8 spur gears turning 24 spur gears.
- Gear Train Two is a trick question. It is a set of idler gears where each gear merely passes the power
on to the next without altering the ratio significantly. Do you notice any differences between it and
the other gear trains?
- Gear Train Three is five sets of 8 spur gears turning 24 spur gears.
- Gear Train Four is four sets of 8 spur gears turning 16 spur gears.
- Gear Train Five is a worm gear turning a 24 toothed crown gear allowing the
8 spur gear to turn the 24 spur.
