ELI5: How the heck a pully system makes a 2 ton safe light as a feather.

Imagine trying to lift a 2 tonne car a metre. Can't do it?

Now imagine pushing it up a very slight 1 metre hill. Much easier. You've done the same amount of work, but spread over a longer distance, so the force required is much less.

Pulleys do the same. Smaller load over a longer distance.
