And if I'm reading the Pdf correctly, it looks like they are using modulus of elasticity in the equation and my preference would be to have that field be elongation (if that is possible). Again, I'm not sure if what I'm looking to do is that easy to do to since I know very little (not even...

Yes, they do indeed publish elongation and minimum breaking strengths, but I'm looking to build a shock load calculator based on an input load, length of rope payed out, distance of fall, and elongation of rope. That's stuff they don't publish because the shock load values change depending on...

Ultimate goal here is to have an Excel spreadsheet that we can post on our websites so other SAR team and rope techs could use this (and input their own data) to give them an idea of shock forces when doing rope training and considering the potential of a high directional anchor failing, etc.

Here's another equation I found that I think is close to what I want to do, but there's a lot of things in it I don't understand.

This is the best I've found so far: https://wilmes.co/risk-control-calculators/fall-protection-force-calculator/?weight=250&fall=3&stop=1&confirm=What+is+the+Force Our rope lengths will vary so would need the calculator to consider various lengths relative to the elongation. In other words...

Thank you!

Thank you. I wasn't sure where to put it.

Sorry about posting my question before making my introduction. I'm a search and rescue tech that works a lot with mechanical advantage and various rope systems. Every so often I have a physics question that comes up and was just looking for a good forum to post questions on.

Im new here and don't have a clue for the most part so don't beat up on me too much, but I'm looking for an equation that is simple enough for an idiot like me to understand. I’m looking to build a shock force calculator in Excel (if possible). I’ve found the actual equation online but the...
