So you can't be wrong. Just. Wow.

Standard scientific method, dummy. Go look it up. Theory always yields to test results. Reality never yields to theory.

First, welcome back Dave!



This stuff about springs is pretty standard and simple physics. I typed the word "springs" in my browser and it offered "springs in series" as maybe the fourth item to search for. Searching for that gave a wikipedia article called "spring in series", several physics web sites and also YouTube videos on the subject.

Here is a simple explanation:
http://www.cyberphysics.co.uk/topics/forces/springs_series_parallel.html
And another from a company that makes springs:
http://www.acxesspring.com/calculate-rate-of-springs-in-parallel-in-series.html

Please don't feel like things need to become a fight when we're talking about stuff, we all have stuff to learn here....

True, if you're testing a new hypothesis and your test results don't match the theory, then probably the theory is wrong or something was overlooked. However, the scientific process also allows for repeatability. If you're testing a known principle that has been tested many times before and your results don't match the theory or the results of every other person who has performed the same experiment, then odds are high there is a problem with your experimental set up rather than the theory being wrong and every other experiment before yours being wrong.

Also, be careful slinging personal insults on a forum like this. While I'm sure you have a lot of experience in certain automotive fields, there are many people on here who are much smarter than you or I and a vast range of experience.

Are you absolutely sure about that? I reckon I can name at least two...

But in any case, so far as patents are concerned, a helical spring is a helical spring - its intended use is irrelevant.

For the benefit of all us dummies, can we see a picture of your test setup for measuring the rate of a single spring and then two or more of the same spring in series? You're trying to overturn a very well understood and trusted physical principal here. As they say "Extraordinary claims require extraordinary evidence".
