By themselves, pulleys don't do much. But when they work together, they provide something called mechanical advantage! Want to see more content? Check out our other videos at astrocampschool.org/blog/

Thank you. Believe it or not I watched several videos before this one and none of them explained how, even with demonstrations, pulleys work. I could have saved so much time if they explained the weight is half as much because there are two ropes lifting the weight, plus you explained the length of the rope. Physics teachers rambled on for 15 minutes and didn't mention these two key facts.

No problem! Once you start adding pulleys and more rope, it becomes way easier to lift things up!

Great explanation. Thanks. Anyone able to help me? I want to use a pulley to raise a parachute onto a ridge line and avoid needing to undo the ridge line. What could I use to lock the rope off once the parachute is hoisted, locked both in horizontal position along the ridge line and also vertically once raised by the Pully? itself. For vertical locking, would either clam cleat or cam cleat work?

the thing that confuses me is saying that increasing distance reduces force. if i had a rope to pull a heavy thing but just had it go really far and pulled it in a straight line the same amount of force would be necessary than if there were no ropes

Is there a way to have an on the fly modular pulley system? One where you can use a 2:1 advantage and then change it to a 1:1 advantage with minimal effort for actually changing the cable/rope routing?

You can do the same thing with 1 pulley as you did with 2. Just tie of one end of the rope to frame and have weight hanging between the tie off and the pulley.

Do the wheel of pulley have to always rotate? Can there be a pulley which doesnot rotate and the rope just slides through the circumference of it? Will such pulley give mechanical advantage?

Good point and not at all obvious. The pulley, having bearings at its centre, reduces friction. It would work if it DIDN'T rotate, but friction -- of rope sliding against pulley -- would be greater.

Politely I think your schooling is wrong... It is not split up between these two ropes... Is it not the mechanical advantage held within the circumference of the pulley wheel.. so correctly you should say that the wait is split up between the leaver advantage of the pulley wheels...

Not totally accurate. You put in the same amount of work regardless of how many pulleys and ropes because you have to pull that much farther
