The MOI goes up with a radius squared relationship. That is, if the same amount of mass is moved twice as far away from the axis of rotation it will have 4x the MOI effect.


It's been a while but I remember a formulae for polar moment of inertia of a disc being ID to the 4th power.Where I was a constant. This accounts for the increase in area as the radius increases. But it's been a while !.......
