Can a tiny fast gear lift a heavy crate?
The little gear whirls when the crank turns. Its spool and rope lead to a crate resting on the floor. The fast spin is easy to see. What will happen when the crate pushes back?
One meeting point controls both wheels
Each amber tooth meets one teal tooth. Neither wheel can skip ahead at the contact.
Tap one tooth-step at a time
One amber tooth passes; one teal tooth passes. The counts stay matched.
Fewer teeth means more turns
This toy measures turning speed only. The load test is still ahead.
One crank turn makes three output turns
Now we know the small gear's speed. What happens when a load resists?
Two matched cranks get the same push
Same-size crank handle. Same push. Same spool. Same heavy crate. Only the teal output changes: one is small and fast; one is big and slow.
Neither crate has moved yet. Which box can begin the lift?
Same-size crank. Same push. Same spool. Same heavy crate.
Which gearbox gets its crate off the floor?
Push both matched crank handles with the same effort.
