The easy way to keep this all straight is:
1) Do the whole calculation for a solid bar of the outside diameter.
2) Do the whole calculation for a solid bar of the inside diameter.
3) Subtract the inside-diameter stiffness number from the outside-diameter
stiffness number.
Those using astute mathematical reasoning will deduce that the advantage of
tubular sway bar over a solid sway bar of the same stiffness is that the
tubular bar is less massive. Reducing the mass of a competition car is
generally a Good Thing.
