... From definition of moment of inertia (I = Σi mi ri2 ), we can see that the system on the right has the movable masses closer to the rotation axis, which gives it a lower moment of intertia and from τ = Iα the angular, and thus the linear, accelertation will be faster. So the mass on the left will hi ...
