I'm looking at my garage door extension springs and I got to wondering:

Google says:
The force required to extend an extension spring is proportional to the distance it's stretched.

So.. looking at the attached picture, how does all that force being exerted on the spring while stretched not snap the tiny little area of metal in the circle?

Coming from a layman's term that a chain is only as strong as its weakest link, I find it incredible that such a small area (as compared to the entire spring) can sustain the forces applied to it without breaking.

Does this mean that the area in the circle is 'feeling' the same forces applied to the spring further down?

In your experiance, is the circled area typically the first place to break?
