Re: [ATM] Aluminium or stainless steel?

Huh?
Suppose the tubing is made of gum rubber. I stuff it with a
tight-fitting rod of steel. Doesn't it become stiffer?
Instead, suppose I plug each end and then fill the tube with something
under pressure, doesn't it become stiffer also? (V14gra effect,
so to speak).
When a piano string is tightened, does it require more force to deflect it?
