One question: Do you have a rough idea what the increments are between the levels on the orange spring? I'm wondering how many 64 rubber bands I'd have to put on the top of the vulcan before I equal the next spring level...
-
Exactly what I was looking for. Cheers mate!

Hey Joe how come I cant find ur armwrestling training videos on youtube anymore and why did you stop making the videos. I was really benefitting from ur knowledge. Please start ur armwrestling training videos again.

The force of 1.5lb is acting upon a moment about 205mm from the fulcrum, the handle end about 125mm from the fulcrum, so the force at the handles end will be about 2.46lb and NOT 1.5lb! Do you see what I'm saying now Joe?
You could verify the theory by testing with an adapted RGC, this would IMO give you a more accurate measurement.

You'll know how much tension is acting on the ends of the vulcans loading tines but it won't be an increase of 1.5lbs resistance on the close, you'd be better of getting some new numbers on an adapted RGC if you really needed to know the numbers.
I know what feels like 1/4, 1/2, 3/4s of a level and add bands accordingly.

Great stuff Joe!

I gotcha autoplus! I failed to take into account the leverage at the end of the handles.
The whole purpose of the video was to give users an idea of just how much resistance they were adding with a given resistance (#64 rubber band). Just a simple way to keep up with their progressions and know how much resistance they were adding. Thanks for the clarification and keeping me on track here my grip friend!!!

Thanks for the comments guys!
Autoplus, if it takes a known amount of weight to stretch a #64 rubber band a known length and these bands are place in the same position everytime, YES the weighted resistance is known unless you care to explain different. With a #64 rubber band at notch 11 on a Vulcan with the handles closed it measures 9". It takes 1.5 lbs. to stretch the same band 9". To me me the physics is a no-brainer. No dis-respect either. Physics don't get any easier than this.
