Mithiwithi: More likely he measured, say, 135 feet of rope on the ground and failed to account for it stretching by more than 5 feet under load.Still, ouch.
largedon: As a math teacher I look forward to using this story the next time some smart ass kid asks me why he needs to learn math.
AsprinBurn: I haven't watched the video, but I assume folks were trying to outdo each other by progressively getting closer and closer to the ground. So he wins?
Bastard Toadflax: It turned out Utah was his [puts on sunglasses]...arch enemy.Yeeeeeeaaahhh!
DenisVengeance: Math is hard
I AM THE GOAT: DenisVengeance: Math is hardMath is easy, but I'm sure the ground was hard...
ZeroPly: Mithiwithi: More likely he measured, say, 135 feet of rope on the ground and failed to account for it stretching by more than 5 feet under load.Still, ouch.135 feet of dynamic kernmantle can stretch about 20% under load, which would be an additional 27 feet. Generally that happens only on a long lead fall. But on a swing, the initial shock loading while not perceptible might still stretch it significantly, from which it won't recover during the entire arc.PSA: Climbing rope is for climbers, so please stay the f*ck away from it if you don't know how it behaves. Gravity behaves differently on the wall than it does in Mountain Dew commercials.
meyerkev: largedon: As a math teacher I look forward to using this story the next time some smart ass kid asks me why he needs to learn math.Of course, if Mithiwithi is right, they really need to learn physics./Namely, conservation of energy as applies to springs// .5m(h + l)^2 = .5kh^2 Solve for h, where l is the length of the rope and h is the additional height needed to stop falling./// If l + h > 140 feet, you will DIE.
