I am working on making a system of pulleys and a lever. I am planning on using a complex pulley with a few blocks. I wanted to know what how much weight is taken off with the addition of each pulley. If anyone knows some of the equations involved it would be much appreciated. I was planning on lifting about 200 lbs.
