I have a question about pulley
I have a question about pulley.
There is fixed pulley: http://en.wikipedia.org/wiki/File:Polea-simple-fija.jpg where you need to use e.g. 100N to lift 100N.
There is moveable pulley: http://en.wikipedia.org/wiki/File:Pulley1a.svg where you need to use e.g. 50N to lift 100N.
Question: How does "reversed moveable" pulley look like, i.e. the one where I need to use 200N to lift 100N? I need it for my home gym.

Google images for a block and tackle, or a mobile crane block. Once you see one rigged up your answer should be self evident.
