Consider this pulley:

There has been some discussion at a forum whether this pulley reduces the necessary force to 1/2 or to 1/3 of a "non-pullied" rope. I'm strongly for 1/3 basically since for each distance the lower pulley moves all 3 ropes are moved = 3 times the distance = 3 times less force. I'm just posting this here to get a more accurate answer since, well, it's a physics forum :).
