 Pedantically, sure ...
 

It's not the *direction* that defines the catenary but the uniformity of
force over length - which - you'd have known if you had ever taken physics.

 ...but pragmatically, the reason why catenary doesn't apply to laeral non-gravitational based forces is because it is difficult for them to be sufficiently homogeneous: this theoretical doesn'tpragmatically occur in reality.
 Case in point, if this factor really was as significant as you're trying to imply that it is, then the real world ramifications are that during races, there would *never* able to be any passing in corners.

And he's simply wrong.
The forces in rope/chain/etc. hanging between points (i.e. in a catenary curve) is most definitely NOT uniform.
The the ends of rope/chain/etc. need to support the weight of all the material that hangs below, whereas the middle of the hanging whatever doesn't.
(If he hadn't hidden himself away from me, I could easily write him a thought experiment by steps, where I could absolutely prove that fact so completely that he'd have to agree or shut his eyes to truth.
Little Arlen is probably remembering what he was taught in high school physics where they say that the tension in an idealized rope (/chain/etc.) is the same everywhere *
* and where there's probably a footnote that says "ignoring the weight of rope itself".
Guys like him hear/read the first explanation of such phenomena they're give and never are able to move beyond it.
