    The Body Language of Trees - A handbook for failure analysis

    Found the attached doc. Couple choice excerpts: "Mechanical properties of wood Parallel-to-grain properties. The parallel-to-grain direction is the strongest and stiffest from a structural perspective. The tensile strength of softwoods parallel to grain at 12% moisture content generally ranges...

    The Body Language of Trees - A handbook for failure analysis

    I had the same question when I heard this one. I would like to see some empirical data from compressive and tensile failure testing. Keep in mind that comparing the compressive strength of wood to tensile strength of wood does not equate to saying that wood is weak in compression. It's all...

    WTB Rope Runner Pro

    I believe it. If I'm not mistaken, for the ascent event he footlocked, but since he had none of his gear he somehow used the extra tail of the rope to tie the footlock prussic. I might be remembering that wrong but he did something funky that passed inspection.

    WTB Rope Runner Pro

    I use the 11.7 lines. Currently have hyper climb for my long rope and blue moon for my mid and short ropes. I've been using the hhxf for the last couple years and don't exactly want to swap but I feel like I should be familiar with some of the more commonly seen devices in the field. Expand...

    WTB Rope Runner Pro

    So I ended up buying a red/black color schemed one from Monarch Ropes for $329 shipped. That seemed like a hell of a sale so bit the bullet and got it. The unique color helped sway me too. These damn tree gear manufacturers sure got my number...

    The Body Language of Trees - A handbook for failure analysis

    Buddy of mine found this book and sends me one passage a day. I've found them to be written in an interesting tone/perspective and have decided to share them here. I will add one per day, as I get them. 1. "Wound wood has a primary function to repair the mechanical support system, not to stop...

    Replace this rope?

    Silver ivy is a double braid with a 6,500 lb MBS. Half the load is on the cover. Half the load is on the core. Even if you completely sever the cover, that rope will still hold 3,250 lb. The little bit of damage in your picture would not worry me. I'd be more concerned with how that section runs...
