I suppose in a way this is Hooke's Law. It's kind of my own law though in a way. Hooke's Law uses a constant (k, F = -kx) but my test will show you distance (x) and force (F), because you calibrated it, so the constant k doesn't really matter. If you want to, you can determine k my testing a bunch of different weights, but this is really a rough way of doing it with any kind of spring you can think of. No equation necessary. Hope that answered your question.
most digital scales have lag, most analog scales max out at like 20 lbs usually. Also, the springs are changeable here so you can test large or small engines. Lastly, its just cooler to have your own thrust meter than to use your parent's scale. :)
What is it...Hooks Law? Can you post the calculation?

Why not use a scale?
