what is an elastic?

in what sense is a steel spring not an elastic?

if a cart is driven by a twisted rubber band (like a rubberband
propellerdriven airplane) is the rubber band acting as a spring
or as an elastic

or both?

I suppose that spring materials can store energy without changing length very much---by torsion and bending

and I suppose elastics store energy by changing length

But I am just guessing. Is there an official definition
of what an elastic is? sorry I can't help. Just curious.

I understand, thanks. So your project is to make a rubberband
powered cart.

What performance category is most important to you?
speed? distance (range) on the level? hill-climbing ability?
load-bearing?
