No I appreciate the observation, thanks. From what I have learned in this thread though, there is an important distinction between torsion springs (essentially bombs that can shred you to pieces due to stored up energy) and extension springs (more like a trampoline -- no stored up energy until you extend them). This spring is the latter.

That makes a lot of sense. Here is the spring, btw, which I was able to find with the help of this distinction:

So basically whereas a torsion spring is always already under tension, and thus has a ton of potential energy stored up, an extension spring is not under tension until it is extended (like a trampoline), is that right?
