But since you pulled Alan G. Baker's post out of my killfile, notice that
the catenary is one of the most fundamental curves, where the morons think curves can only be in the Y axis but there's nothing stopping curves from existing on the x axis (or any axis for that matter, even 4D spacetime).

"This race report features two cars named "Typical" and "Best" racing
on an Official AWANA Track with a catenary transition... The Track
Profile follows with the name of the track and its configuration...
Because a catenary transition model was selected, specifics of the
catenary transition appear below the character sketch of the track.
Marks in the track sketch represent the track surface..."
The problem with the Apple trolls is they have no education so they don't know even the most basic of curves, which, let's face it, are important.
The important aspect of a catenary is the force exerted is uniform with respect to length of the catenary curve - which is important to racing.
This is HILARIOUS folks!
After what must have been HOURS of scouring the web, Arlen has finally
found a page that mentions "catenary" in a "racing" context...
...but it's about Pinewood gravity cars!
'My hope is that this serious simulation program will help you use,
experiment with and get a better feel for the physics of the race
detailed in the Grand Prix Science Manual and the reasons behind the suggestions in How To Make A Fast Pinewood Car. But more than just
changing design parameters to see the effect in virtual races, Race It!
is an attempt to give you the ability to tune YOUR Grand Prix car design concepts on your organization's track before you build!'
Pinewood cars are homebuilt model cars designed to race down ramp onto a straight section of track.

Arlen is using a single reference to using a catenary as the curve to transition a wooden ramp to horizontal track...
...for cars made by Boy Scouts!
LOLOLOLOLOLOL!
