What have we learned about energy absorption when it comes to dynamic activities that test the limits of ropes and wood? For one, we’ve learned that tensile strength alone is not all it’s cracked up to be. For example, no one needs to spell out the result of bungee jumping using high-strength cable instead of (significantly weaker) elastic rope.Although an extreme example, the physics are virtually identical when arresting other falling loads, including tree parts. No, not because the load shouldn’t be injured, rather to lessen forces capable of cracking an anchor point or snapping high-strength ropes. Not only are such shattering forces the inspiration for modern tree cabling systems like Cobra and TreeSave, but they are also the reason many arborists are choosing Dynasorb for wood-dropping activities, too.Note: Tensile Strength is Average Break Strength with a splice.
