Hello hello! Licensed Mechanical Engineer here. Not to be pedantic, but the track wouldn't be in "tension". It would be in bending (a combination of tension and compression).

Happy to elaborate further if it is valuable to the discourse!

I read that as "binding", i.e. the joints between the pieces being under stress and transmitting force.

Sure, can you create a bending (momentum?) diagram for that course? :D
