We’ve all seen the videos. Those crushers where the two cylinders with teeth roll towards one another and just obliterate everything.

How?

Answer 1

The power of gear boxes pretty much.

If you have a motor than has 20lbs of torq, put it on a gearbox that’s 30:1 (30 input rotations= 1 output rotation) then, all of a sudden, your motor is producing 600lbs of torq.

Can also work the opposite way to.

If you have a motor that runs at 20RPM, put it on a 1:30 gearbox, then that motor now has an output of 600RPM.

A gearbox pretty much scales up or down the input values.
