Sheesh, well said mate heheh
something to the effect of heavier rotating mass = larger rotational interia
= more resistance to changes in rotational velocity. also, the greater the
distance the mass is from the axis of rotation, the more it effects
rotational inertia ie this is why material is removed from the outer edge,
it has a greater effect on the rotational inertia than the same amount of
material removed from the inside of the flywheel
