What got me was that the beam looked as though the balance points were
at 25%, 50% and 75% of the beam length, giving leverages of 1:3, 1:1 and
3:1. I got very frustrated.
The book clue is that only one segment of the little ball has been
changed, and you can see it, so the composition of that ball is known.
That narrows down the options a lot.
Eventually, with the aid of a spreadsheet to calculate the options for
the large ball, it becomes obvious that you can't arrange a 1:1 or 3:1
configuration. Only 2:1 and 4:1 are possible...
