Hey all, I realize that when weight is moved from the center of a flywheel toward the outer edge (or a larger diameter wheel is used), the capacity for energy storage increases. But I have no idea how to calculate how much that increase actually is, or whether the increase remains constant (proportionately) between the two as RPMs increase. Anyone have a formula handy for this? Hopefully with enough footnotes for a "non-engineer" who doesn't know many standardized formula abbreviations... Thanks, moo __________________ moo (moo') adj.
