TORQUE the LINE EXPERIMENT - SPECTRA FAIL
https://www.youtube.com/watch?v=_hfNdqYC9wA&t=1s
Mitchel Stinson from Australia has cancelled his designed Torque the Line experiment, because the line chosen for the test, Spectra fishing braided line, was found BY HIM to be not as strong as advertised.
If or when he gets a refund from the braided line company, Mitchel asserts that he will refund the moneys contributed to this project.
We at FlatEarthLunacy have communicated with Mitchel several weeks ago, and stated that should the experiment as designed produced results, his findings would forever be inconclusive and subject to controversy.
The shape of gravity induced Catenary Curve is well established in physics. But his proposed experiment introduces several additional variables outside of the standard.
Please keep in mind that Jeranism (Jeran Campanella) was originally going to do this experiment, until Mitchel stepped in and volunteered.
Note: We show below using Mitchel's own video how he incorrectly conducted the Spectra line strength test. He is wrong. The line does hold up to specification, so Mitchel cancelled the experiment needlessly.

The standard Catenary Curve (shape of the drooping chain)...
How is the curve calculated?
The following calculator can be used to determine the displaced cable length and the amount of cable sag, due to Earth's gravity...

What Mitchel wanted to do (stretch the line across water a few kilometers, and verify the curve)...

Here we show that Mitchel tested the line incorrectly, and came up with a wrong conclusion. The line does meet the manufacturers advertised strength.
Maybe you missed this in Mitchel's video, but here the line strength registered AT LEAST 49.88 pounds before it snapped.
Here we see that a hand crank is used to pull the braided fishing line. Each crank to the next sprocket pulls the line in large length increments. When you suddenly pull the line, say 1/4 inch, it can suddenly snap.
Correct testing involves pulling the line in very minute increments until it snaps. That is not what Mitchel did.
We believe his test was conducted incorrectly. The line does meet manufacture's specifications. Therefore, no money will be refunded and all those people who contributed lose out.

Why Mitchel cancelled the experiment:
In his words, because the line chosen for the experiment was not strong enough.
But our analysis photos from Mitchel's own test video, shows that the line is as strong as rated = 50 pound strength.
Our analysis and conclusions:
1. We advised Mitchel that the experiment line used needed to be heavy non-stretchable.
2. We advised Mitchel that having the line touch and sink below the water line (which he wanted to do) invalided the use of the available standard catenary curve calculators. Line in the water has to contend with additional local variables (i.e., buoyancy of the line, the exact length of the line in the water, wave, current & temperature conditions, etc.) that the standard calculators were not setup to handle.
3. Mitchel was advised by an engineer not to conduct the experiment in salt water. Salt water changes the buoyancy of the fishing line, based on actual salinity and temperature. But Mitchel did some buoyancy calculation and insisted that salt water was fine for the experiment. We continued to disagree. This just adds another layer of variability that can change the shape of the catenary curve.
4. Whatever test results he came up with would always be in dispute, because too many external influences and experimental variables other than gravity, would affect the shape of his braided line.
