Gordy - going fishing for a couple of days so have to be
brief.
With respect to gravity - the mass of the rod remains constant even
though its weight changes on
the moon. This is the mass that is essential for F=ma.
With respect to air resistance - this will definitely contribute to rod
bend but it should be a small
amount because the surface area of the rod is small. A quick experiment
would be to try driving
with a rod sticking out a window.
Cheers!
Walter
