ELI5: What exactly is a pulley/pulley system doing that creates a mechanical advantage?
I find the concept of a 3:1 and 5:1 pulley system absolutely mind boggling.
Obviously, the force is all being handled by the same piece of rope, but somehow it becomes easier to pull heavy things by running more rope through a bunch of pulleys.
I understand that single pulleys work by changing the direction that force needs to be applied.
How on Earth does doing that multiple times make things easier to pull?
