Re: Lightened Flywheel?
Here is the math. So if you reduce the diameter by half and keep the mass the same you reduce the inertial to one-fourth. If you also remove weight by machining off the outside diameter you will reduce the inertia even more, to 1/16 if my calculations are correct. The weight of a lightened flywheel is taken off of the outermost radius so the effect is more than what you would expect by just comparing the weights.
