hi all have a basic question about chain strength that I'm unsure about.
Ok so from what I can understand about rope and pulleys (without being to scientific) if a rope is run around a pulley, it will effectively double the capacity or halve the load on each strand. A quick qoogle search suggests that the single strand is under friction/compression etc so doesn't take the full load. Probably not doing a very good job of explaining but I'm sure you'll know what I'm trying to say lol.
Ok so here is my scenario, was having a few beers with my mates the other day and we were finishing up a silage pit. One bogged his grader and the other walked the digger over and I hook the chain up. Single chain hook each end, I run the chain through the drawbar on the grader and hook both ends on a loop on the digger bucket. My mates makes the comment why did I bother to double the chain there is only one link around the drawbar pin. You guys can see what I'm asking, I'm not sure he is correct?
