Searching for the Hardest Possible Climbing Fall - P.1
-
0:00 - 0:03I have some new toys today
-
0:03 - 0:05which reminded me
this famous physics lecture. -
0:08 - 0:12[Music]
-
0:14 - 0:17Well, more on toys later.
-
0:17 - 0:19But now here is a quiz for you.
-
0:19 - 0:23Which fall do you think
is harder for the climber: -
0:23 - 0:24this one
-
0:24 - 0:27[Music]
-
0:29 - 0:32or this one?
-
0:34 - 0:37That was sick.
-
0:37 - 0:39So a really hard indoors fall
-
0:39 - 0:42where we intentionally created
a lot of drag -
0:42 - 0:44by zigzagging the rope.
-
0:44 - 0:47And then belaying
in the hardest way we could. -
0:50 - 0:54Or a massive outdoors whipper?
-
0:54 - 0:57Which do you think was
harder for the climber? -
0:57 - 0:59[Music]
-
0:59 - 1:03So if you're one of these
99 percents of the people -
1:03 - 1:06who think that you know the answer
-
1:06 - 1:09wait for it. Because it's not that simple
-
1:09 - 1:10and I've been there and I'm gonna
-
1:10 - 1:12explain throughout this video.
-
1:12 - 1:15But actually the main motivation for me
-
1:15 - 1:18for this video was not to just
compare these two falls -
1:18 - 1:21but to measure what are the forces
-
1:21 - 1:26on really really hard
real climbing falls. -
1:26 - 1:27And now you might ask:
-
1:27 - 1:28Who cares?
-
1:28 - 1:32Like... numbers... whatever...
-
1:32 - 1:33Rope...
-
1:33 - 1:34A fuzzy rope...
-
1:34 - 1:38happens. We keep falling and
falling and falling. -
1:38 - 1:40And the rope gets more and more damaged,
-
1:40 - 1:41more and more fuzzy,
-
1:41 - 1:45and in some extreme cases
-
1:46 - 1:48very damaged. Like this one
-
1:48 - 1:52got really really really erect
-
1:52 - 1:55yum yum yum yum
-
1:57 - 1:59And now the real question is
-
1:59 - 2:02how dangerous this is.
-
2:02 - 2:04Could i break
-
2:04 - 2:07this rope on real climbing fall?
-
2:07 - 2:10If I would have taken
a couple of more falls -
2:10 - 2:12would it have snapped
-
2:12 - 2:13or no?
-
2:13 - 2:18So the first idea how to test this
was very simple. -
2:18 - 2:20Just go outside and make a bunch of falls
-
2:20 - 2:22and see if it's gonna snap.
-
2:22 - 2:24Obviously by having some backup -
-
2:24 - 2:26rope or something.
-
2:26 - 2:29But yeah nobody would want to take
-
2:29 - 2:32a bunch of really really hard falls
-
2:32 - 2:34again and again and again and again
-
2:34 - 2:36and then to make it
-
2:36 - 2:38to hit that spot at the same spot
-
2:38 - 2:40and again and again and again.
-
2:40 - 2:42It would be pretty difficult.
-
2:42 - 2:43So instead I decided
-
2:43 - 2:44to reach out to Mammut
-
2:44 - 2:48and ask if I could come and
play with their drop tower. -
2:48 - 2:51So this is where
the rope testing magic happens. -
2:51 - 2:55Basically every rope manufacturer
has a facility for -
2:55 - 2:56testing ropes.
-
2:56 - 2:59Unfortunately so-called standard test
-
2:59 - 3:01is really really hard.
-
3:01 - 3:04What are the forces on standard tests?
-
3:04 - 3:07Um... like around for a single rope
-
3:07 - 3:10it's around like 8 to 9 KN...
-
3:10 - 3:11Pretty much impossible
-
3:11 - 3:13to reach in real life scenarios...
-
3:13 - 3:17And my guess it would just
snap this rope instantly. -
3:17 - 3:19And that's not what i wanted to do.
-
3:19 - 3:23I wanted to reduce to modify that test
-
3:23 - 3:27to be more or less like
really really hard realistic fall. -
3:27 - 3:29And for that I needed to know
-
3:29 - 3:30what are the real forces
-
3:30 - 3:34on really hard falls.
-
3:38 - 3:41Ha-hah, hard is easy...
-
3:41 - 3:44And to do so it was
a good time for me to visit -
3:44 - 3:45Andy from LineGrip
-
3:45 - 3:48And get myself a couple of these.
-
3:48 - 3:50It's basically a device
that can measure forces. -
3:50 - 3:56It's the only device you can have logging
-
3:56 - 3:57for a specific amount of time
-
3:57 - 4:00without connecting any other device to it.
-
4:00 - 4:03Like there's scales or load cells.
-
4:03 - 4:06But you have to attach
a notebook... a laptop... -
4:06 - 4:10And that would be quite complicated
especially for him -
4:10 - 4:12to take a laptop with him...
-
4:12 - 4:14And no this video is not sponsored.
-
4:14 - 4:15I bought this
-
4:15 - 4:18and the other one myself.
-
4:18 - 4:22Well, so technically it's sponsored
by my curiosity -
4:22 - 4:24and by good people who support me
-
4:24 - 4:29by visiting my website www.hardiseasy.com
-
4:29 - 4:33So what's your estimate?
-
4:33 - 4:34Oh I have to estimate the peak force?
-
4:34 - 4:37Yes, of course.
Ah that'll be -
4:37 - 4:392.95
-
4:39 - 4:432.95? Yeah!
-
4:43 - 4:45Well, um as a developer
you have to be precise -
4:45 - 4:49It's 2.95
OK 2.95 Right. -
4:49 - 4:50Uh 3.1
-
4:50 - 4:522.5
-
4:52 - 4:55What's your guess? 2.7 2.7
-
4:55 - 4:57And what do you wish for?
-
4:57 - 5:01What's you wish for? Zero... 1.5 please
-
5:01 - 5:031.5
-
5:03 - 5:06So obviously to get real data we needed
to do real falls. -
5:06 - 5:11And doing really really hard falls
with real humans -
5:11 - 5:13is sketchy.
-
5:13 - 5:17So if for whatever reason
you will decide to repeat this - -
5:17 - 5:20don't!
-
5:27 - 5:302.56
2.5 already -
5:30 - 5:34How does 2.5 feel?
-
5:34 - 5:35Soft.
-
5:35 - 5:36Soft? Yeah.
-
5:36 - 5:38OK let's try harder.
-
5:38 - 5:40So our plan was to start soft
-
5:40 - 5:43and then keep making
harder and harder falls -
5:43 - 5:47where the belayer would do basically
the opposite of the soft catch. -
5:47 - 5:52Basically as hard as he can.
-
6:04 - 6:06Yeah but that looked like a hard catch.
-
6:06 - 6:08This time 2.89
-
6:08 - 6:112.89
-
6:11 - 6:13Yeah.
-
6:13 - 6:15That's close to three kilonewtons already.
-
6:15 - 6:16But the fall this time...
-
6:16 - 6:18How was the fall?
-
6:18 - 6:21It felt much more harder than before.
-
6:21 - 6:23Yeah I would say it was okay...
-
6:23 - 6:26It doesn't feel hard? No it was not hard.
-
6:26 - 6:30But it wasn't soft so.
-
6:30 - 6:37That's a sacrifice for the experiment.
-
6:37 - 6:39I feel sorry for you.
-
6:39 - 6:42No problem. No problem, no problem?
-
6:42 - 6:43His hands are bleeding... No problem...
-
6:43 - 6:46'For science!' as Ryan says
'For science!' -
6:46 - 6:47For science!
-
6:47 - 6:50What's your weight by the way? 72.
-
6:50 - 6:52And yours, susan? 78.
-
6:52 - 6:55So we swapped.
-
6:55 - 6:57At some point we realized
-
6:57 - 6:59that making really hard falls
-
6:59 - 7:01just by belayer efforts
-
7:01 - 7:03is not gonna be enough
-
7:03 - 7:08so we decided to introduce
extra friction in the system. -
7:08 - 7:11Ah that's a nice workout :)
-
7:11 - 7:12Advanced course
-
7:12 - 7:15So how does it feel to fall
on your own equipment? -
7:15 - 7:16That feels cool.
-
7:16 - 7:20But let's see how it feels falling at all.
-
7:20 - 7:23Because I'm such a good climber
I never fall. -
7:23 - 7:28Aah. So maybe you should watch my videos
about fear of falling. -
7:28 - 7:31And to play safe since
we switched the system a little bit -
7:31 - 7:36we started with a soft catch.
-
7:49 - 7:53So how did it felt for you? 1.6 KN.
-
7:53 - 7:54It was... The fall was cool.
-
7:54 - 7:56But the swing was enormous.
-
7:56 - 8:00Don't jump backwards when you fall
-
8:00 - 8:01Jump forward?
So i have to... -
8:01 - 8:03No-no, just let go...
-
8:03 - 8:08Um yeah! This is actually
a very common mistake by beginner -
8:08 - 8:10fallers
-
8:10 - 8:15is to push or jump away
from the wall during the fall. -
8:15 - 8:18Obviously the harder you
push away from the wall -
8:18 - 8:21the bigger the pendulum
into the wall gonna be. -
8:21 - 8:24And your legs are not gonna be happy.
-
8:24 - 8:27So don't jump to the outside.
-
8:27 - 8:30Yeah! just let go straight down.
-
8:30 - 8:31Don't touch the rope!
-
8:31 - 8:32One,
-
8:32 - 8:34two,
-
8:34 - 8:36three.
-
8:38 - 8:42So you got only 2.1
-
8:42 - 8:44How does that felt?
-
8:44 - 8:49Uh I couldn't tell the difference
to before. -
8:49 - 8:53Except that the wall contact wasn't there.
-
8:53 - 8:57No difference. Hard one. Hard one.
-
8:57 - 8:59But in this time
when you fell straight down -
8:59 - 9:01you did not touch the wall at all.
-
9:01 - 9:05Great! It'll be hard but it won't hurt.
-
9:06 - 9:09Come on! Three, two,
-
9:09 - 9:10one.
-
9:10 - 9:13Oh!
-
9:16 - 9:172.6
-
9:17 - 9:22Oh my god, that was crazy.
-
9:34 - 9:37That was crazy and it's...
-
9:37 - 9:41and it's only 2.6 KN.
-
9:41 - 9:44So how was this fall for you?
-
9:44 - 9:46Again it was perfectly okay
-
9:46 - 9:49except for the wall contact. That was...
-
9:49 - 9:51That was pretty hard this time
-
9:51 - 9:54So
-
9:54 - 9:56even harder
-
9:56 - 9:58without me jumping out.
-
9:58 - 10:01So, dummy. Yeah?
-
10:01 - 10:03As hard as possible.
-
10:03 - 10:05So don't jump out!
-
10:05 - 10:12One, two, three.
-
10:15 - 10:162.8
-
10:16 - 10:19At this point we had a ton of drag.
-
10:19 - 10:22The belayer belay as hard as he can.
-
10:22 - 10:26And we reached 2.8 KN
of force to the climber. -
10:26 - 10:28But Andy really wanted to reach
-
10:28 - 10:31his 2.95 estimate.
-
10:31 - 10:33So we decided to increase
-
10:33 - 10:36the distance of the fall a little bit
-
10:36 - 10:39Yeah, that's the drag.
-
10:39 - 10:42Yeah, that's enough, I think.
-
10:42 - 10:46That's enough, just start with that.
-
10:46 - 10:51And don't forget to let go.
-
10:51 - 10:54One, two, three.
-
11:09 - 11:102.9
-
11:10 - 11:132.9, it's very close to your guesstimate.
-
11:13 - 11:17You said 2.95 is your guess.
-
11:18 - 11:20I gotta go again.
-
11:20 - 11:23Take this much more rope.
-
11:23 - 11:24Yeah, no.
-
11:24 - 11:26We actually maxed out what we can do
-
11:26 - 11:28in that climbing gym
-
11:28 - 11:30and trying to make even bigger fall
-
11:30 - 11:31would result into the fall
-
11:31 - 11:33which is too close to the ground.
-
11:33 - 11:36But we had another test candidate.
-
11:36 - 11:37And what's your weight?
-
11:37 - 11:4065kg
-
11:42 - 11:47One, two, three.
-
11:51 - 11:522.9
-
11:52 - 11:542.9?
-
11:54 - 11:56And quiz number two.
-
11:56 - 11:58How can a lighter climber
-
11:58 - 12:02generate the same force
as the heavier one? -
12:02 - 12:07Well let's take a look again.
-
12:10 - 12:12Whoa
-
12:12 - 12:15Do you notice the difference?
-
12:17 - 12:20So the lighter climber
fell more straight down -
12:20 - 12:23resulting into pretty much all the force
-
12:23 - 12:24going into the rope.
-
12:24 - 12:27While the heavier climber
jumped out a little bit. -
12:27 - 12:30That increased the pendulum.
-
12:30 - 12:32So there is less force into the rope.
-
12:32 - 12:35And more force into the pendulum.
-
12:35 - 12:36Or into the wall...
-
12:36 - 12:38Or into your ankles.
-
12:38 - 12:40So here is a mini model
-
12:40 - 12:41to demonstrate that.
-
12:41 - 12:45If i take a 10 kilogram of mass
-
12:45 - 12:50and drop it next to the anchor
-
12:50 - 12:54I get 2.67KN
-
12:54 - 12:56Now if i do this again
-
12:56 - 13:00but i step a meter back
-
13:02 - 13:06I get 2.1 KN
-
13:06 - 13:09Because a bunch of force
went into the swing. -
13:09 - 13:12If I would try to
-
13:12 - 13:16even increase the swing more...
-
13:22 - 13:25Now the force was only 1KN.
-
13:25 - 13:27So how was that last fall?
-
13:27 - 13:29Oh it was hard...
-
13:29 - 13:32Have you ever got a fall
that hard on real rock? -
13:32 - 13:35No, never
-
13:35 - 13:38Almost or not close?
-
13:38 - 13:40Yeah there was one that was close,
-
13:40 - 13:43but not as hard as this one.
-
13:43 - 13:47So still your estimate is off...
-
13:47 - 13:52By 0.03
-
13:52 - 13:54Shame on me!
-
13:54 - 13:55That was close.
-
13:55 - 13:58That was very close.
-
13:58 - 14:01Do you know that our max
-
14:01 - 14:04was exactly the same?
-
14:04 - 14:07He had 2.92 and I had 2.92.
We... -
14:07 - 14:08Ah so maybe that's
-
14:08 - 14:13the universal limit of the hard fall?
It is! -
14:13 - 14:16We found it! Yeah!
-
14:16 - 14:18So a couple of takeaways from this.
-
14:18 - 14:21First obviously it's really hard to design
-
14:21 - 14:24a real life experiments
to be very precise. -
14:24 - 14:27Because it not only depends on
-
14:27 - 14:29how high the fall was,
-
14:29 - 14:30how heavy the climber was,
-
14:30 - 14:32how hard the catch was.
-
14:32 - 14:34But also how much
-
14:34 - 14:37the climber jumped out from the wall.
-
14:37 - 14:40So that's another thing to consider.
-
14:40 - 14:43And obviously a practical takeaway
-
14:43 - 14:45is that the harder you push yourself away
-
14:45 - 14:48from the wall or jump away from the wall
-
14:48 - 14:51the harder you will smack back
into the wall. -
14:51 - 14:55We have a game. If you squeeze it
-
14:55 - 14:59it reads a number. Can you explain why?
-
14:59 - 15:03Oh, yeah! It's a material deformation.
-
15:03 - 15:03Uh,
-
15:03 - 15:08there's two uh wow you call it
-
15:11 - 15:14cut.
-
15:14 - 15:16There's two strips that measure the
-
15:16 - 15:18material deformation.
-
15:18 - 15:20When you pull this you can't see
-
15:20 - 15:22but the material stretches.
-
15:22 - 15:23And these strips measure that.
-
15:23 - 15:26And the electronics convert that
-
15:26 - 15:29through a voltage that changes
-
15:29 - 15:32through the stretch of the strips.
-
15:32 - 15:34And so if you press
-
15:34 - 15:37you also deform the material.
-
15:37 - 15:40Just in a different way but
-
15:40 - 15:43the strips just register
material deformation. -
15:43 - 15:46So you can go like this
or you can go like this -
15:46 - 15:47It's the same.
-
15:47 - 15:49So basically long story short.
-
15:49 - 15:51What are we gonna do with this now?
-
15:51 - 15:52Oh, we're just gonna play a game with
-
15:52 - 15:54who gets the highest number.
-
15:54 - 15:56Number is irrelevant,
doesn't mean anything... -
15:56 - 15:57But...
-
15:57 - 15:59Oh yeah it does. If it's the highest
-
15:59 - 16:01you're the best.
-
16:01 - 16:04Okay let's see. Go!
-
16:04 - 16:04Me?
-
16:04 - 16:07Of course!
-
16:07 - 16:09Uh, zero.
-
16:09 - 16:11All right.
-
16:11 - 16:14So don't show my hand behind...
-
16:22 - 16:24A scream at 0.4
-
16:24 - 16:25You can do better,
do this. -
16:25 - 16:27Yeah but I use only three fingers,
so um... -
16:27 - 16:29No, do it again...
-
16:29 - 16:30No let's give it fair.
-
16:30 - 16:32I'll try a left hand.
-
16:32 - 16:34No-no, just do the strongest best.
-
16:34 - 16:38Give it your best
-
16:38 - 16:40No way, no chance.
-
16:40 - 16:43This is for two.
Yeah, but it wasn't me... -
16:43 - 16:45Who was it?
-
16:45 - 16:48Look at the big guy.
-
16:48 - 16:51Look at this guy.
-
16:52 - 16:54Once again.
-
16:55 - 16:59Wait, wait! We haven't
even seen the result. -
16:59 - 17:02Well, at least you're getting red.
-
17:02 - 17:050.68
-
17:05 - 17:08That's for a right-hander
who works in the office. -
17:08 - 17:09Yeah.
-
17:09 - 17:11But he just did with left hand.
-
17:11 - 17:14Yeah, but he's right now the right hand...
-
17:17 - 17:1976
-
17:19 - 17:21Oh, no!
-
17:21 - 17:22Oh, no-no.
-
17:22 - 17:27What does it mean: 'Oh, no!'?
-
17:35 - 17:3964 We'll try again. We'll try again.
-
17:41 - 17:42Oh.
-
17:42 - 17:43Oh, no.
-
17:43 - 17:4859 59 That's not possible.
-
17:48 - 17:51Once again, once again, once again
-
17:56 - 17:58What was yours, I forgot?
-
17:58 - 18:0176
-
18:01 - 18:04So who is going to beat his record?
-
18:04 - 18:07Try again, try again, beat him.
-
18:08 - 18:10Oh no, it's not getting any...
-
18:10 - 18:11You should either try passad
-
18:11 - 18:14I didn't scream like 'a-a-ah'.
-
18:14 - 18:17Go, go with scream, let's see if it helps.
-
18:19 - 18:22No, it's not getting any higher.
-
18:22 - 18:24No, it has got lower.
And don't put that in the video! -
18:26 - 18:27No, I won't.
-
18:27 - 18:30This is not in the video that
you're watching now... -
18:30 - 18:31No, no, no.
-
18:31 - 18:33Let me try.
-
18:33 - 18:36Wait, wait! It says 0.01 already.
-
18:36 - 18:40So I'm winning already by...
karma. -
18:40 - 18:43Let's see, it's already...
He's scared of it. -
18:43 - 18:45Let's see how should I go like full hand
-
18:45 - 18:47or just the finger.
-
18:47 - 18:49Yeah maybe it's a technique thing.
-
18:49 - 18:50He's not really strong.
-
18:50 - 18:53He's just got the best technique.
-
18:53 - 18:54OK.
-
18:54 - 18:59It was a bigger scream than the result.
-
18:59 - 19:01Yeah.
-
19:01 - 19:01OK.
-
19:01 - 19:0771. I still need 0.3 to match him.
-
19:07 - 19:09How hard do you climb?
-
19:09 - 19:11Sorry? How hard do you climb?
-
19:11 - 19:12Very hard...
-
19:12 - 19:15Very hard?!
-
19:15 - 19:17I've found the trick.
-
19:17 - 19:18Oh, no.
-
19:18 - 19:20Oh, no. Wait, you did it behind your back.
-
19:20 - 19:24What was it?
-
19:26 - 19:28No way!
-
19:28 - 19:31What? No, I feel that i'm cheating.
-
19:31 - 19:33So the trick is that
-
19:33 - 19:35before what i was trying was this.
-
19:35 - 19:37Yeah, right. So what else?
-
19:37 - 19:40But now I did this.
-
19:40 - 19:43And that gives me way.
-
19:43 - 19:45Wait, oh...
-
19:45 - 19:46Yeah...
-
19:46 - 19:48I am, thanks...
-
19:48 - 19:50But what if you twist it even more?
-
19:50 - 19:51So you go from corner to corner.
-
19:51 - 19:53So basically my grip is strongest
-
19:53 - 19:54in this position.
-
19:54 - 19:57That's why i get more. Yeah.
-
19:57 - 19:59Yeah, he's getting
seven something already. -
19:59 - 20:01OK, let's go.
-
20:01 - 20:05Are you ready? Zero...
-
20:12 - 20:13OK, so...
-
20:13 - 20:14This.. let me...
-
20:14 - 20:17Let me just show mine.
-
20:17 - 20:20No.
-
20:20 - 20:22That's good compared to before.
-
20:22 - 20:25You were talking about challenge.
-
20:25 - 20:28And, uh, we could do that challenge.
-
20:28 - 20:33And LineGrip corporation would sponsor
-
20:35 - 20:37two thousand dollars
-
20:37 - 20:39for the challenge winner.
-
20:39 - 20:40Can i get it?
-
20:40 - 20:41I've won already. No?
-
20:41 - 20:43So let me get this straight.
-
20:43 - 20:44Like if I travel around
-
20:44 - 20:46and give this to people?
-
20:46 - 20:49Yeah. Does that count or no? Yes.
-
20:49 - 20:51It counts? Yes, it counts.
-
20:51 - 20:52OK.
-
20:52 - 20:53Because so far i'm winning...
-
20:53 - 20:54Most of all,
-
20:54 - 20:57you're like the guinness book juror.
-
20:57 - 20:59You check that they don't cheat.
-
20:59 - 21:00So, so far i'm winning. Right?
-
21:00 - 21:03If nobody presses harder than this
-
21:03 - 21:04I get 2 000 euros.
-
21:04 - 21:07True. Nice.
-
21:07 - 21:10OK, I know that you want to try.
-
21:13 - 21:17Do you want to try double?
