Graph Text

I took a load of measurements at approximately every half inch. I have made a graph to show the way the rate raises. I started with a bit of tension because of the way I set the test up. The best part of the graph is between 14" and 18". I used two 22" bungees and stretched them to 44".so the diagram starts when the chords are stretched to 26". I am going to try bicycle inner tube tomorrow with and without air.
