	Moment of Inertia
		Moment of inertia is a measurement of the 'rotatibility' of an object.
		The moment of inertia of mass around an axis of rotation (assuming an infinitely stiff connection) is the mass multiplied by the square of the distance to the rotation axis.
		The additional moment of inertia generated by a stabilizer depends on three factors: mass, distance of mass to the bow rotation axis and the stiffness of the stabilizer rod.
