1. The problem statement, all variables and given/known data A man stands on a board of negligible mass with a length of 10m is supported by 2 cables, one on the left on one on the right, with a tension of 300N and 200N respectively. How much does the man weigh in Newtons? 2. Relevant equations F=ma Torque= F*lever arm 3. The attempt at a solution I'm tempted to just 500, but that's far to simple. I thought of setting up a torque equation, but I don't know how I would when I don't know his mass or where he stands. So, if I assume he's standing x meters from the left: 300(x)-200(10-x) + man(mans location) = 0. So I set one of the cables as the axis of rotation: the left cable, giving me man(x)=200(10). Multiply out to get man(x) = 2000. Now I have two variables I can't get rid of. But I still really want to just sum all the forces along the y axis and set it equal to zero: 300 + 200 -man = 0, so I still get 500. Am I just overthinking the hell out of this?
