im 103 lbs. and i want to know if some really thin paracord can support my weight!! -M
Of course you can! It is called 550 cord because it has a minimum breaking strength of 550 pounds, hence the name 550 cord. -BLUEBLOBS2

I want to make a graplling hook.
Paracord can support 500 and 50 pounds! I am shure it can lift a 103 lbs boy! DDDDDDDDDUUUUUUUU!!!!!!!!!!! Trust me I work with that stuff all the time You can make an elevator with that stuff!!
It could support a 103 lb girl, but a 103 lb guy? Not so much
That's what I heard too.
I mean, its only logical, right?
It is. Because guys have some sort of property that girls don't that makes paracord break if they weigh 103 pounds.
Indeed. In the meantime, this will be referred to as the "Masculo-paracord Uncertainty Principle, for lack of a better term.
That sounds like a great name for it.
I'm pretty sure thats true at any weight, its probably not specific to individuals at 103 pounds. I'm also pretty sure it applies to most materials too.
Perhaps it's especially true at 103 pounds?
That is quite possible. Maybe this difference reoccurs several times across varying masses? Methinks a mathematical formula is in order along with some handy-dandy graphs, it will require the help of everyone at instructables.
Not only must the graphs be handy dandy, they must also be official looking.
You do have a big point there, as only the most official looking graphs are taken seriously. Would you mind helping me test the theory out? (I'd take gmjhowe's advice on the procedure, it sounds safe)
I'd love to help, and then we could publish a report on our findings.
That's a fantastic idea! Although we need a multitude of vic-- err, volunteers in order to collect data.
Yes, we must gather some "volunteers".
Gather is such a harsh word, I'd go with collecting, or rustling/rounding up, or herding, those all sound better(especially if used in the same context as cattle).
"550 Paracord" is so-called because it can support up to 550 pounds. There is a brief summary of the various cord strengths here.
Flanimal: just be advised that a "breaking strength" metric is for static weight. A person can generate several times their body weight by dynamically loading a line.
And I almost forgot--putting a knot in any rope reduces it's breaking strength significantly--something like 40-60%.
That depends on the knot - any decent book of knots should tell you how much any particular know reduces the strength of the line.
Yes, the type of knot very much matters (why I offered a range.) I'd give yourself a safety margin of 10 or 20%, too. If I were going to trust my life to it...
I can think of one easy way to find out. Make sure to put a mattress under you, and not string yourself that far off the ground (like only a foot away from said mattress)
