But why does the rope wrap around the central stick? That's the one thing they don't explain. It goes through the hole at the bottom of the central stick and the pulley is attached to that. There must be a reason that rope wraps around the central stick and the pulley isn't just tied to the bottom of the stick. Des anybody know?
Youtube @christmassnow3465 2 days ago The pillar works more like a crane (to move things around) than as a lever (lifting). However, the force multiplier is in the reel which pulls the rope: The reel winds the rope around a thin cylinder. The workers spin the cylinder with long handles. This is how a reduction gear works. It reduces the speed but increases power.
