WEBVTT 00:00:00.000 --> 00:00:01.280 [Music] 00:00:01.280 --> 00:00:03.840 so here is a cool fact 00:00:03.840 --> 00:00:06.560 rope manufacturers claim that no matter 00:00:06.560 --> 00:00:09.280 what fall you will take on a dynamic 00:00:09.280 --> 00:00:10.719 climbing rope 00:00:10.719 --> 00:00:12.320 the impact 00:00:12.320 --> 00:00:17.080 is unlikely to injure you 00:00:18.320 --> 00:00:20.000 that was sick 00:00:20.000 --> 00:00:21.680 so how does it feel this 00:00:21.680 --> 00:00:26.320 impact on a huge outside whipper 00:00:26.320 --> 00:00:29.439 or this is even better how does it feel 00:00:29.439 --> 00:00:32.239 to fall while trying to clip a second 00:00:32.239 --> 00:00:37.680 quick draw and get a really hard catch 00:00:39.440 --> 00:00:42.480 so can this impact injure you does it 00:00:42.480 --> 00:00:44.559 hurt 00:00:44.559 --> 00:00:45.440 or 00:00:45.440 --> 00:00:46.879 even better 00:00:46.879 --> 00:00:48.719 how does it feel when i'm trying to 00:00:48.719 --> 00:00:50.800 explain all of this 00:00:50.800 --> 00:00:54.320 and almost kill myself 00:00:55.840 --> 00:00:59.680 so yeah that happened and it all started 00:00:59.680 --> 00:01:02.879 with my wish to measure the forces of 00:01:02.879 --> 00:01:06.080 really really hard climbing falls 00:01:06.080 --> 00:01:08.799 and knowing these forces allow me and 00:01:08.799 --> 00:01:11.040 probably others to answer a lot of 00:01:11.040 --> 00:01:13.760 important questions for us climbers 00:01:13.760 --> 00:01:16.799 like can you break a dynamic climbing 00:01:16.799 --> 00:01:21.759 rope which is really really worn out 00:01:23.600 --> 00:01:26.399 on realistic climbing falls 00:01:26.399 --> 00:01:27.300 some people 00:01:27.300 --> 00:01:29.920 would say that it is impossible to break 00:01:29.920 --> 00:01:32.400 this rope while others would freak out 00:01:32.400 --> 00:01:33.680 seeing this 00:01:33.680 --> 00:01:35.920 because it doesn't look that great to be 00:01:35.920 --> 00:01:37.119 honest 00:01:37.119 --> 00:01:40.000 so stick with me the answer to this is 00:01:40.000 --> 00:01:41.040 coming 00:01:41.040 --> 00:01:45.280 and it actually surprised me a lot 00:01:45.280 --> 00:01:49.680 but now back to hard falls 00:01:53.119 --> 00:01:55.360 so in previous episode we went to a 00:01:55.360 --> 00:01:58.000 small climbing gym in germany and we 00:01:58.000 --> 00:02:00.799 tried to create the hardest climbing fall 00:02:00.799 --> 00:02:03.680 by creating a ton of drag 00:02:03.680 --> 00:02:09.079 and belaying in some crazy crazy ways 00:02:11.200 --> 00:02:13.440 and then i had a quiz for you 00:02:13.440 --> 00:02:16.890 which fall do you think was harder for the climber 00:02:16.890 --> 00:02:19.520 this crazy slam 00:02:19.520 --> 00:02:24.319 or this big outdoors whipper 00:02:29.920 --> 00:02:33.280 so if you think that the big fall 00:02:33.280 --> 00:02:35.200 looks softer 00:02:35.200 --> 00:02:38.000 good because i thought exactly the same 00:02:38.000 --> 00:02:40.720 thing and pretty much any person to whom 00:02:40.720 --> 00:02:42.485 i showed these two clips 00:02:42.485 --> 00:02:44.119 i'm gonna show you two falls 00:02:44.140 --> 00:02:46.080 and you can try to guess which one was 00:02:46.080 --> 00:02:48.400 harder to the climber - okay 00:02:48.400 --> 00:02:51.040 yeah i can already tell you 00:02:51.040 --> 00:02:53.200 well theoretically i would say that the 00:02:53.200 --> 00:02:55.791 second one in the gym is the harder fall 00:02:55.791 --> 00:02:58.640 because it's a shorter rope that can 00:02:58.640 --> 00:03:01.360 absorb or a shorter portion of the rope 00:03:01.360 --> 00:03:03.360 will absorb the energy 00:03:03.360 --> 00:03:05.599 since there's so much zigzag happening 00:03:05.599 --> 00:03:08.239 in the rope line and therefore yeah not 00:03:08.239 --> 00:03:10.481 the entire rope that is actually used 00:03:10.481 --> 00:03:15.160 so let's see if that's actually true 00:03:15.160 --> 00:03:18.159 [Music] 00:03:18.159 --> 00:03:19.520 that was sick 00:03:19.520 --> 00:03:25.519 [Music] 00:03:25.519 --> 00:03:27.760 that was sick 00:03:27.760 --> 00:03:30.879 that was like a massive fall 00:03:30.879 --> 00:03:31.994 it was 00:03:31.994 --> 00:03:33.330 falling was nice 00:03:33.330 --> 00:03:36.560 how big you think the fall was 00:03:36.879 --> 00:03:39.760 how hard to say i will say like 00:03:39.760 --> 00:03:42.080 eight meters maybe 00:03:42.080 --> 00:03:44.480 it looked massive from the side it 00:03:44.480 --> 00:03:45.999 looked massive 00:03:45.999 --> 00:03:47.519 maybe 10 00:03:47.519 --> 00:03:49.680 i don't know 00:03:49.680 --> 00:03:52.000 do you think it's more than 10 00:03:52.000 --> 00:03:53.680 yeah from the side it looks massive 00:03:53.680 --> 00:03:56.400 I think more it was more to 15 i would say 00:03:56.400 --> 00:03:57.200 you know 00:03:57.200 --> 00:03:59.680 you don't think so 15 00:03:59.680 --> 00:04:01.599 no i don't think so i don't think so 00:04:01.599 --> 00:04:03.760 yeah judging the distance of 00:04:03.760 --> 00:04:06.959 the fall is always tricky but by my best 00:04:06.959 --> 00:04:09.599 estimation before the fall he was around 00:04:09.599 --> 00:04:12.239 two and a half meters above the bolt and 00:04:12.239 --> 00:04:14.959 after the fall he was about eight meters 00:04:14.959 --> 00:04:18.160 below the bolt so let's say 10 meters 00:04:18.160 --> 00:04:23.280 and this 10 meters fall resulted into 00:04:24.199 --> 00:04:28.479 3.4 kilonewtons of force and if we 00:04:28.479 --> 00:04:31.360 compare that to the jim slam 00:04:31.360 --> 00:04:35.360 that slam was only 2.6 kilonewtons and 00:04:35.360 --> 00:04:37.680 the hardest fall in the gym that day we 00:04:37.680 --> 00:04:42.960 got was 2.9 kilonewtons this one 00:04:42.960 --> 00:04:46.639 so does it mean that this huge whipper 00:04:46.639 --> 00:04:48.847 was harder than the slam 00:04:48.847 --> 00:04:52.194 it doesn't look like that right 00:04:52.194 --> 00:04:55.040 and to make sense out of all of this we 00:04:55.040 --> 00:04:58.639 need to define what does it mean harder 00:04:58.639 --> 00:05:00.880 what we measured is the peak force to 00:05:00.880 --> 00:05:03.600 the climber's harness and this peak 00:05:03.600 --> 00:05:08.080 force happens around this moment 00:05:08.080 --> 00:05:13.339 [Music] 00:05:13.440 --> 00:05:15.520 and if you look closely this doesn't 00:05:15.520 --> 00:05:17.759 look that bad 00:05:17.759 --> 00:05:20.000 and what gets our attention is actually 00:05:20.000 --> 00:05:23.039 the contact to the wall imagine if this 00:05:23.039 --> 00:05:27.280 wall would have been not overhanging 00:05:27.280 --> 00:05:30.160 then the peak force on the dynamometer 00:05:30.160 --> 00:05:32.320 to the climber's harness would read 00:05:32.320 --> 00:05:34.880 exactly the same but the slam to the 00:05:34.880 --> 00:05:37.600 wall would be much worse and that's by 00:05:37.600 --> 00:05:39.520 the way how most of the people sprain 00:05:39.520 --> 00:05:42.639 their ankles shortfall hard catch 00:05:42.639 --> 00:05:45.520 super quick slam into the wall so how 00:05:45.520 --> 00:05:47.919 hard the fall for the climber is will 00:05:47.919 --> 00:05:50.479 depend on two things first is the 00:05:50.479 --> 00:05:53.840 initial impact to the harness this 00:05:53.840 --> 00:05:56.000 that we measured to be around three to 00:05:56.000 --> 00:05:58.160 three and a half kilonewtons on hard 00:05:58.160 --> 00:06:02.160 falls let's test how three kilonewtons 00:06:02.160 --> 00:06:03.680 feels 00:06:03.680 --> 00:06:06.319 on the harness 00:06:06.319 --> 00:06:09.440 don't do this at home 00:06:15.520 --> 00:06:18.520 ouch 00:06:21.840 --> 00:06:24.160 told you not to do this at home 00:06:24.160 --> 00:06:25.759 listen learned 00:06:25.759 --> 00:06:28.160 falling on a single bolt on three 00:06:28.160 --> 00:06:30.160 kilonewtons of force 00:06:30.160 --> 00:06:34.560 can make an entire bolt come out 00:06:34.560 --> 00:06:35.600 of 00:06:35.600 --> 00:06:41.039 18 millimeters of shitty spanish plywood 00:06:44.000 --> 00:06:45.199 so 00:06:45.199 --> 00:06:47.520 the impact was 00:06:47.520 --> 00:06:49.280 okay 00:06:49.280 --> 00:06:51.759 but the landing on the ass was 00:06:51.759 --> 00:06:53.199 not so okay 00:06:53.199 --> 00:06:54.240 all right 00:06:54.240 --> 00:06:57.919 don't do this at home number two 00:06:57.919 --> 00:07:00.639 since i really want to experience three 00:07:00.639 --> 00:07:02.560 or three and a half kilonewtons of force 00:07:02.560 --> 00:07:05.120 to my harness so i can tell you 00:07:05.120 --> 00:07:06.800 how that feels 00:07:06.800 --> 00:07:08.800 i rigged another system 00:07:08.800 --> 00:07:10.160 which is 00:07:10.160 --> 00:07:12.400 hopefully not gonna end up like the 00:07:12.400 --> 00:07:13.680 first one 00:07:13.680 --> 00:07:15.759 this time it's very static but it 00:07:15.759 --> 00:07:17.440 doesn't matter 00:07:17.440 --> 00:07:21.120 i just want to feel it 00:07:22.479 --> 00:07:23.599 wow 00:07:23.599 --> 00:07:26.720 that was 3.8 00:07:26.720 --> 00:07:29.720 kilonewtons 00:07:30.319 --> 00:07:34.319 and actually that felt quite okay 00:07:34.599 --> 00:07:37.440 3.1 kilonewtons 00:07:37.440 --> 00:07:41.360 and i barely feel anything 00:07:43.280 --> 00:07:45.840 three and a half 00:07:48.000 --> 00:07:51.360 okay this was almost four kilonewtons so 00:07:51.360 --> 00:07:53.520 under three kilonewtons 00:07:53.520 --> 00:07:56.000 i don't feel anything between three and 00:07:56.000 --> 00:07:59.039 four i get a little but that's far from 00:07:59.039 --> 00:08:00.319 injuring me 00:08:00.319 --> 00:08:01.360 and 00:08:01.360 --> 00:08:05.440 my homemade climbing wall breaks at 00:08:05.440 --> 00:08:08.879 3.8 kilonewtons to default which would 00:08:08.879 --> 00:08:11.840 be around 2 kilonewtons to the climber 00:08:11.840 --> 00:08:12.720 so 00:08:12.720 --> 00:08:14.479 my homemade climbing 00:08:14.479 --> 00:08:16.879 wall is not for 00:08:16.879 --> 00:08:19.520 falling and the second thing that the 00:08:19.520 --> 00:08:21.759 climber will experience is of course the 00:08:21.759 --> 00:08:25.360 impact to the wall which as we saw might 00:08:25.360 --> 00:08:28.319 be problematic in fact let's zoom in on 00:08:28.319 --> 00:08:30.400 the big fall and watch it couple of 00:08:30.400 --> 00:08:32.879 times 00:08:36.640 --> 00:08:41.479 and now let's compare it to the gym fall 00:08:45.360 --> 00:08:47.920 so as you can see it's not that easy to 00:08:47.920 --> 00:08:50.640 tell which one was actually harder and 00:08:50.640 --> 00:08:53.680 it also depends a lot on climbers skills 00:08:53.680 --> 00:08:56.560 to absorb the impact with his legs as a 00:08:56.560 --> 00:08:58.399 climber you basically need to be like a 00:08:58.399 --> 00:09:01.279 cat when you hit the wall super soft and 00:09:01.279 --> 00:09:02.959 people who do a lot of baldering they 00:09:02.959 --> 00:09:05.120 tend to be much better because they fall 00:09:05.120 --> 00:09:07.040 on the crash pads a lot 00:09:07.040 --> 00:09:09.200 and falling on a crash but with stiff 00:09:09.200 --> 00:09:12.560 legs would probably kill you so the same 00:09:12.560 --> 00:09:15.040 applies to falling on ropes you want to 00:09:15.040 --> 00:09:18.080 absorb the impact as soft as possible 00:09:18.080 --> 00:09:20.080 and of course there are other factors 00:09:20.080 --> 00:09:21.920 that contribute to how hard you will 00:09:21.920 --> 00:09:24.399 slam to the wall for example jumping 00:09:24.399 --> 00:09:26.399 away or pushing yourself away from the 00:09:26.399 --> 00:09:28.959 wall as i talked in the previous episode 00:09:28.959 --> 00:09:30.160 or 00:09:30.160 --> 00:09:33.360 belaying in really hard ways in gym case 00:09:33.360 --> 00:09:35.839 we created a hard catch on purpose 00:09:35.839 --> 00:09:38.640 however on outdoors whipper the belayer 00:09:38.640 --> 00:09:42.480 was standing and doing nothing 00:09:48.399 --> 00:09:51.200 handbag 00:09:51.200 --> 00:09:53.279 and i have a separate video coming where 00:09:53.279 --> 00:09:55.279 i will show that standing and doing 00:09:55.279 --> 00:09:58.080 nothing creates much harder catch than 00:09:58.080 --> 00:10:00.959 pretty much any soft delaying method you 00:10:00.959 --> 00:10:03.839 can try so although this belay didn't 00:10:03.839 --> 00:10:06.720 looked hard it was definitely possible 00:10:06.720 --> 00:10:09.680 to make it much softer but this was 00:10:09.680 --> 00:10:11.839 actually perfect because i got the force 00:10:11.839 --> 00:10:14.560 to the climber on big whipper on hardish 00:10:14.560 --> 00:10:15.519 catch 00:10:15.519 --> 00:10:18.720 totally realistic scenario and that's 00:10:18.720 --> 00:10:20.480 actually not all 00:10:20.480 --> 00:10:22.320 in the following months i was going 00:10:22.320 --> 00:10:25.700 around and making a ton of experiments 00:10:25.700 --> 00:10:27.360 [Music] 00:10:27.360 --> 00:10:29.839 during which i recorded the forces to 00:10:29.839 --> 00:10:33.279 the climber on over hundreds of faults 00:10:33.279 --> 00:10:35.920 and even ryan sent me some clips of his 00:10:35.920 --> 00:10:39.120 to compare the datum 00:10:41.040 --> 00:10:42.320 oh 00:10:42.320 --> 00:10:44.320 oh that was better than wheaties in the 00:10:44.320 --> 00:10:45.440 morning 00:10:45.440 --> 00:10:50.160 i hit 1.14 i got 2.64 and the hardest 00:10:50.160 --> 00:10:52.700 fall i recorded was this one 00:10:52.700 --> 00:10:55.869 [Music] 00:10:56.800 --> 00:11:01.839 okay okay you saved me 00:11:02.160 --> 00:11:05.800 this is the hardest recording you've got 00:11:05.800 --> 00:11:07.440 3.60 00:11:07.440 --> 00:11:09.200 so in this case we were filming an 00:11:09.200 --> 00:11:12.240 episode of how to belay sketchy close to 00:11:12.240 --> 00:11:14.399 the ground falls 00:11:14.399 --> 00:11:16.720 the climber was clipping the second 00:11:16.720 --> 00:11:19.279 quick draw above his head and takes a 00:11:19.279 --> 00:11:22.279 fall 00:11:22.750 --> 00:11:28.079 [Music] 00:11:28.079 --> 00:11:30.160 so that's another sneak peek into the 00:11:30.160 --> 00:11:31.920 future what's coming on my channel and 00:11:31.920 --> 00:11:33.760 if you don't want to miss that i hope 00:11:33.760 --> 00:11:36.560 that you do youtube things and subscribe 00:11:36.560 --> 00:11:39.040 and click all of these bells and stuff 00:11:39.040 --> 00:11:41.680 but for now i can say that unless the 00:11:41.680 --> 00:11:44.800 climber is really really heavy 00:11:44.800 --> 00:11:47.519 or we are in some unlucky multi-pitch 00:11:47.519 --> 00:11:50.880 scenario which i haven't had time yet to 00:11:50.880 --> 00:11:54.000 experiment with creating a fall which 00:11:54.000 --> 00:11:57.440 would be harder than four kilonewtons 00:11:57.440 --> 00:11:58.959 to the climber 00:11:58.959 --> 00:12:02.320 is really really unlikely and that's 00:12:02.320 --> 00:12:04.560 really good to know because it just 00:12:04.560 --> 00:12:07.519 shows how great the climbing ropes are 00:12:07.519 --> 00:12:10.320 at keeping us safe as i've just 00:12:10.320 --> 00:12:13.200 demonstrated here four kilonewtons to 00:12:13.200 --> 00:12:15.839 climbers harness is not really something 00:12:15.839 --> 00:12:18.480 we should worry about unless of course 00:12:18.480 --> 00:12:20.320 it's accompanied by a 00:12:20.320 --> 00:12:23.040 slam to the wall and that brings me to 00:12:23.040 --> 00:12:24.880 the original question 00:12:24.880 --> 00:12:28.639 can i snap this very worn out rope on 00:12:28.639 --> 00:12:31.440 the realistic climbing fall 00:12:31.440 --> 00:12:34.000 or now i can rephrase the question can i 00:12:34.000 --> 00:12:37.360 snap this rope on forces below 4 00:12:37.360 --> 00:12:40.240 kilonewtons to the rope and the answer 00:12:40.240 --> 00:12:43.839 to this surprised me a lot i had a 00:12:43.839 --> 00:12:45.519 chance to hang out with mamamoo 00:12:45.519 --> 00:12:47.920 engineers and test this 00:12:47.920 --> 00:12:50.639 and also ask pretty much any question i 00:12:50.639 --> 00:12:53.360 wanted and man that was super 00:12:53.360 --> 00:12:55.839 interesting so i recommend to not miss 00:12:55.839 --> 00:12:58.800 the next episode and until then i'm 00:12:58.800 --> 00:13:01.120 gonna leave you with somebody who really 00:13:01.120 --> 00:13:02.880 likes challenges 00:13:02.880 --> 00:13:05.880 okay 00:13:07.120 --> 00:13:10.399 that left hand is 29. 00:13:10.399 --> 00:13:12.720 no i think sitting is better it's all 00:13:12.720 --> 00:13:14.410 about technique 00:13:14.410 --> 00:13:18.010 [Music] 00:13:18.160 --> 00:13:23.279 it's better it's 8 68 now 00:13:23.360 --> 00:13:25.519 okay pressing as hard as you can with 00:13:25.519 --> 00:13:27.510 one hand 00:13:27.510 --> 00:13:34.080 [Music] 00:13:34.399 --> 00:13:36.880 he's going slow 00:13:36.880 --> 00:13:39.120 he's he's weaker than i 00:13:39.120 --> 00:13:40.240 yeah 00:13:40.240 --> 00:13:42.480 really 00:13:44.000 --> 00:13:45.440 what 00:13:45.440 --> 00:13:48.399 how how much do you do i don't say it ah 00:13:48.399 --> 00:13:50.160 and to make this competition a little 00:13:50.160 --> 00:13:53.040 bit more fair i decided to split it into 00:13:53.040 --> 00:13:56.480 1 000 for guys and 1 000 for girls and 00:13:56.480 --> 00:13:59.120 to make it even more interesting girls 00:13:59.120 --> 00:14:01.519 can win both categories of course if 00:14:01.519 --> 00:14:03.920 there is a girl who is stronger than 00:14:03.920 --> 00:14:06.320 the guys 00:14:11.440 --> 00:14:13.920 not better yeah you can grab in any way 00:14:13.920 --> 00:14:14.959 you
