Hi, would you mind if I share my experimental data here? Thanks

Sure, I will do that :)

Sure. I will do that and share the plot. Thanks.

I am planning to first measure the length L0 when load cells shows 0 N. Then start moving the linear strange until the thread breaks. Let's say the thread breaks at 1 KN. I can then plot F vs L and would know strain: (L-L0)/L0 for the linear regime. E - young's modulus I know from manufacturer...

Yes, linear stage, linear encoder and a load cell

Yes they weren't cooperating. I will update as soon as I get results from my experiments. Thanks.

Answer from manufacturer: The tensile force is measured by pulling at a speed of 300 mm per minute at intervals of 250 mm and measuring the force at rupture. We are sorry, but we do not disclose detailed data to consumers.

Yes

Thanks. If manufacturer can't provide this data then I can build a small setup to measure the initial and stretched length using a known load.

Thank you for your patience and help. I will share further information from manufacturer.

Please comment.

Ok thanks. I will ask the test specimen length when they found spring rate.

In parallel, let's just assume k = 490.5 N/m F = |kx| = 490.5*3.28 = 1608.8N = 164 Kgf. Max mass for this rope is 100kg so that means it would break. If I take the other root, F = 143.5 Kgf. So in both case rope is going to break. Which root is relevant?
