WebApr 2, 2024 · Until now the rule that mechanical advantage equals 2*no. of moveable pulleys seems to have hold fast, but I am not sure that it works in this case. I am wondering if instead a better rule is that mechanical advantage equals no. of supporting ropes ? For this particular question, would the no. of ropes supporting the load be three or four ?
