Hollow or solid? v.swaybars

[LAFENGAS]

@newman

you sure about that… torsional stiffness is typically a constant. 0,0 intercept… So you can make a solid bar behave in exactly the same manner as a hollow bar… it’s just a matter of cross section design… But you aren’t going to get it to behave as anything other than a linear spring…

i mentioned weight as being the constant.

EDIT:
the weight of a solid shaft …you can’t change the diameter. for a hollow tube, you can design larger diameter with a thinner wall or a smaller diameter with a thick wall and everywhere in between.

EDIT: EDIT:
If the wall thickness is too thin to be stable, the tubing would collapse prematurely. obvious.
