The biggest circle presents somehow more remarkable member than the others. Let therehim be in both sidesthe center of him as much torquethe mass (not as many circles, but as much power to cause- In other words: if there's a rotation aroundaxis in the midpoint of the most remarkable member)biggest circle the torques caused by the weights of all other items -(including the lines) would cancel each other. I guess it will notdoesn't change the meaning of the graph.
I moved a couple of items to satisfy requirement 1. and approximately also requirement 2.
