Need some info on the distances of things from the fulcrum

It would appear, if we define one unit as the diameter of a ball, that the lever is basically three units wide. Although it's not quite accurate, I think we have to assume that in the first example, the balls' centers of masses are 1.5 and 2.5 units out, and the weight ranges from 1 to 3 units out, so it's COM it's 2 units from the fulcrum.


Remember though, this is a problem for "6 year olds," and I don't remember being taught about torque in the first grade. (Not that my experience is anything to go by.)

If you make that assumption, this is actually quite simple.
