That will tell you the tension but it wont tell you the break point percentage for which you will need the core dimension factored in. The issue with respect to this question of breakage is really at what BP% is the string made.

I repeat centimetres, > NOT millimetres. I forgot to specify the right character set in my last message, so the division sign got mangled. Here is the correct sequence: *l x f x d x = ÷ 20000 =* JD -------------- next part -------------- An HTML attachment was scrubbed...
