The mass in a flywheel is to minimise engine breaking, not for vibration.
Flywheels exist on more than just engines.
What's the one necessity of a good flywheel, to maintain smooth & prolonged motion? A solid bar will see/suffer the same effect.
You’ll need to explain how it relates to the original question as I don’t follow.
If you start movement in both a solid piece and a hollow piece, the solid will continue moving for a longer period. I believe you'll also find that tube is more rigid than a solid of the same diameter.
a tube is stronger than a solid bar to bend https://www.google.co.uk/search?sou...0j0i131k1j0i10k1j33i22i29i30k1.52.VscLcrhbIQk
couldn't say just I know about strength of tube to solid barI agree, but we’re not talking bending, the question is about vibration

Newton’s second law; if you spin your flywheel with a single blow of a hammer which will move the most? A heavy flywheel or a light one?
Most stiffness is in the outer structure of the box but a solid bar will be stiffer.
I'm just now thinking that the OP deserves a slap for starting this thread.

And have you noticed, op hasn’t chimed in once !!!!!!
probably don't now the answer so keeping shtummAnd have you noticed, op hasn’t chimed in once !!!!!!
try bending solid bar round your knee and then tube u will soon seeNo it isn’t. Your link doesn’t say that.
