Charles
I cannot remember the person who made this claim: ..." a piece of thick
walled tubing is stiffer than a solid rod of the same diameter and
material....therefore, boring a hole the length of the rod will increase its
stiffness."  Is there any truth to this?  Is it true for all metals?  Can
anyone on the list verify this claim?
