This image is a schematic representation of Archimedes lever. The balancing equation is given by
L1 * F1 = L2 * F2. There are many configurations of the L's and the F's that would make it stops rotating.The trivial solution is
F1=F2 and
L1=L2. If that is true then there is only one force and one distance. In any kind of dialectic argument, one always come out the winner and the other the loser. And it so happens that the scale of justice is the one behold by a blind angel.
