Correct me if I'm wrong. But, this is just theoretical mechanical advantage. It doesn't account for friction in terms of the sheave and the bearing it rotates on.
+Yingjie Ren learn the fast way , go to harbor frieght and buy a hoist, take it home and play with it . youll be a engineer in 35 min or less . a chain hoist comprises of a very long chain and two pulleys that would allow even you to lift hundreds of pounds at a time , like an engine block for example.
+Dawson Vandecar they still showing this in school???? dam thought they would have gotten new videos by now....... its been twenty years since i was in school watching this stuff.
