Hi everyone...this one is really really confusing me. My teacher showed a picture up on the overhead of a diagram sort of like this (I attached it). Basically a little scale thing is being pulled by 100N weights on btoh sides (we assume that this 100 N each is fully transfered so its 100N sideways.). Anyhoo, the question was: what will the scale show for the weight/force? I answered 200, the correct answer was 100. My teacher swears on it. I jsut don't understand how it can be that way. The curly things on the right of the scale are springs and the circles are pulleys. Can someone explain this to me?
