I know you've been busy abd have a lot of material for new videos but don't forget about your "how to belay" series. Ep. 6 needs to be redone to show the proper PBUS technique and more important, the episode about literally "how to belay" is not done yet! (how and when to soft catch, slack management, distance to the wall, etc.) Please, please, pretty pleeeaseee xD Amazing content as usual, keep it coming!

So nice to see that you went into the CAMP 4 gym in Germany. It's my mostly visited gym for climbing. Makes me wonder, where you are from :D Greetz Pat

Very cool results!

Fun fact: Health studies love to measure grip strength. For example when it comes to measuring the effect of protein intake in elderly persons.

ayyyy you finally got your line scale

Yeah, cool, this is our Climbing Gym in the Winter... Camp4 in Zweibrücken. We go bouldering there... U climbed at our Sandstone-Rocks? Nice Video with good Information as always! Like ur Channel!

Thanks for your sharing

When he said it wasn’t me, I lost it. That guy is funny as heck.

13:13 Interesting. With the same height from which the weight falls, the kinetic energy at the bottom should be approx the same K=1/2mv^2=mgh So, at the bottom the centrifugal force would be F_c = mv^2/R = 2K/R(approx) reduced with more R. And the net force at the bottom would be approx the peak force if it falls straight down + centrifugal force - recoil (incase the weight stretches the rope away from the bottom part due to which it bounces) _(Not sure if that can be added/subtracted this easily, but it's going to be 2K/R(centrifugal) +/- something)_ 🤔 It'd be bad if the recoil point happens right at the bottom with peak centrifugal force.

The only real paper on rope swings I found was this: www.bigel-labs.de/3.Physik/RopeSwing/RopeSwing#5 It does not talk about forces to the rope but instead about G forces, but shows how they don't peak at the bottom of the swing and instead somewhere along where the rope starts getting tense...

Loved the 2nd part, just a bunch of friends fixiated on a rather dumb thing, teasing each other hahaha

Liked how the Airedale Terrier came running up to the belayer: "are you OK?"

I'm always concerned about the scientificness of videos like yours on KZread. But your videos are, from a scientific perspective, pretty accurate.

TKS!

Nice!

Falling is not hard, just let go. Belaying is hard though. Search for soft catch in climbing.

0:08 you need to remember to keep your face very steady where the movement began, you went like 5cm foward. Dangerous hahahah (thats why Professor Lewin did it touching a wall)

About time.! 😂😉

This gym looks sick tho😍

@11:44 is a perfect example of your fall when you don't jump backwards.

I’d like to see what the forces for the leader are using an ohm device. I always feel like the catch is super hard

@wyattroncin941

How not 2 has a video of a 50 kg belayer catching a 131kg leader using the ohm. 2.9kn with a factor 1 fall, so yeah that's a pretty hard catch.

“Adam Ondra was my coach” 😂

Great Video as always! I'm super curious about a new piece of gear a friend recommended to me. The Edelrid Ohm- Assisted-braking resistor for increasing rope friction when there is a large weight difference between the belayer and lead climber. In the event of a fall, the OHM increases the amount of rope friction to the first bolt so that a lighter belayer can hold a heavier lead climber without difficulty. What is your opinion on this device?

I'll make a video about it some time in not so near future (overloaded a bit), but it's great for what it does, don't know anything better at this day

Hy, i am actually very curios if any of your test buddies, got some back/hip pain out of your science project. As a professionell treeclimber i learned in all of my courses, how severely dangerous even tiny falls into a static rope are. So trying to push the limits of a fall with an elastic rope and a real climber feels a bit crazy to me. Still you aproached the testing quite safely bringing the falling-faktor slowly up and the content was interesting. So thanks from my side!!

@Ikaros23

Жыл бұрын

It`s zero pain. climbing belt ( climbing harness) is over your hip, and the shock off the fall is absorbed by the straps that is attached to the belt and around the thigs of the climber. The climbing rope is almost like a bungee rope and is highly elastic. The real risk is to fall hard into the wall and to break the ancles or hands. To prevent this it`s important that the belayer uses " dynamic belaying" , this technic makes the fall alot softer for the climber

@leeprice133

People do gigantic rope jumps on dynamic climbing ropes - the material has enough elasticity that you can basically fall any distance without encountering high enough forces to cause serious damage.

6:30 Whew, I know that feel.

Good stuff! So can we calculate the max G-force that the body had to suffer in the biggest fall? Off the top of my head, that would be around 4g, no? That is pretty interesting, because in a video I made with bouldering falls the peak force was more than twice as much! Dynamic rope sure does a good job of softening the fall!

I want see Lead Solo forces. Where you're falling close to the anchor

Hi people of the comments section. Would anyone climb with a line scale device to be able to log the force of the falls they’ve taken?

I didn't know that Timothee Chalamet is a rock climber :D

You are in Zweibrücken?!!! 😃👍👍👍

The amount of rope out will modify the amount of force generated.

lol I was in that climbing hall yesterday

8-9KN is spine snapping territory, not rope snapping, probably knot snapping, too.

Wouldn't the z drags actually help soften the fall? The extra friction starts absorbing force before it makes it to the belay device, spreading out the impact, and there is more rope stretch in the system to absorb force overall.

@HardIsEasy

2 жыл бұрын

From my experience on real climbs with a lot of drag or some experiments I saw heavy drag makes a much harder catch for the climber. I guess rope stretch is better at absorbing the impact compared to friction. In heavy friction situations rope close to the belayer doesn't get much load and doesn't stretch that much... Maybe slight friction could actually produce the result you are talking about, but I have no proofs just speculation

Yeah I have had very heavy climbers say "great catch" when they were fairly high up and when they fell but I felt nothing. There was no jump by me bc I felt no force on me at all to jump into. But I thought it was bc there was so much drag bc of so much rope out that the system did all the work.

Hi! waiting for subtitles RU and EN 😊

Push in from the arc to the middle where you tie your rope while reseting maybe? So its resets while in negative values, after that try to do the same thing :D

💪😀

Am i the only one worried about the rope? UIAA ratings for single rope is 5 i recall and if exceeded you should retire the rope? This test exceeded that waaaay much?

14:58 piezoelectric! Probably, anyway.

lesser ropelenght = lesser way for friction. with lesser friction or stretching you have higher forces.

@GuttMedHatt

We should look at the impulse, the soft human body will spend longer time decelerating than a rigid steel plate. So you need less force because you have longer time to apply the force

One fact not mentioned yet is that a lot of energy is diffused in the elasticity of the person's body, resulting in lower force. Drop tests with rigid objects generate much stronger forces.
