In my post above about the plasticity of the relationship between effective mass and compliance, I might better have written that one should make the calculation of Fr for a variety of values of M and C, in order to see that you can get away with some fairly unlikely combinations and still be within an "acceptable" range. In part, this depends also upon what one considers acceptable.
Anyway, I still think Almarg nailed this particular problem. Which has nothing to do with M and C.
