For instance, such a pulley system would likely involve two pullies, one at the top with an anchor and a wheel, and one at the bottom of a loop of rope that goes from the anchor at the top around the bottom pulley and back up over the wheel in the top. when you pull the rope x metres, you're removing x metres of rope from the loop, but becaus its folded in two, each half only looses x/2 metres and thats the height that the bottom pulley moves.
So the amount of rope you move on the other side is equal to half of what you pulled? Oy
what you should get are some more books. physics for dummies or something like that.
I'm in the same boat as Alan except worse. There are no tutors around, as my school has only one Physics teacher.
