Alisse Posted January 3, 2020 Posted January 3, 2020 This caught my eye with the figure eight ..https://www.npr.org/2020/01/02/793050811/a-knotty-problem-solved Advance apologies for how related to climbing this is! Quote
kmfoerster Posted January 4, 2020 Posted January 4, 2020 Thanks for posting that. The image of the color changing fiber with the figure eight is a great visual to how rope is stressed differently because of bends. Whenever you bend a rope, the outside fibers of the sheath and core are under much more stress than the fibers on the inside of the bend. Rope is strongest in a straight pull. Same with webbing, it gets weaker when you introduce twists and bends. Luckily for recreational purposes these reductions in strength are nothing to worry about. I also thought it was quite interesting what they said about knots with opposite twists holding better. I guess it makes sense, just never really thought about it. Quote
