Dialogue: 0,0:12:47.24,0:12:49.92,Default,,0000,0000,0000,,not that trivial now the second problem
Dialogue: 0,0:12:49.92,0:12:51.92,Default,,0000,0000,0000,,comes from saying that if you can't

Dialogue: 0,0:12:54.36,0:12:56.44,Default,,0000,0000,0000,,turns out that measuring cut resistancy
Dialogue: 0,0:12:56.44,0:12:59.20,Default,,0000,0000,0000,,in climbing ropes is a very tricky top
Dialogue: 0,0:12:59.20,0:13:03.80,Default,,0000,0000,0000,,IPC in 2002 UAA proposed a test similar

Dialogue: 0,0:13:10.20,0:13:12.60,Default,,0000,0000,0000,,the problem was the values that we got

Dialogue: 0,0:13:14.48,0:13:17.00,Default,,0000,0000,0000,,were just inconsistent within the test
Dialogue: 0,0:13:17.00,0:13:18.76,Default,,0000,0000,0000,,but also between different institutes
Dialogue: 0,0:13:18.76,0:13:21.40,Default,,0000,0000,0000,,and Laboratories so 2 years later the
Dialogue: 0,0:13:21.40,0:13:24.44,Default,,0000,0000,0000,,test was withdrawn and since then a lot
Dialogue: 0,0:13:24.44,0:13:26.80,Default,,0000,0000,0000,,of different tests were tried out by

Dialogue: 0,0:14:02.84,0:14:05.20,Default,,0000,0000,0000,,either the forces were unrealistically
Dialogue: 0,0:14:05.20,0:14:08.08,Default,,0000,0000,0000,,high or the Dynamics in those test
Dialogue: 0,0:14:08.08,0:14:11.08,Default,,0000,0000,0000,,introduced too much variability meaning
Dialogue: 0,0:14:11.08,0:14:13.16,Default,,0000,0000,0000,,when the Rope is falling on some kind of

Dialogue: 0,0:14:16.24,0:14:20.36,Default,,0000,0000,0000,,the same way so in 2018 edet proposed a

Dialogue: 0,0:15:21.52,0:15:24.24,Default,,0000,0000,0000,,similar but then they took the same rope
Dialogue: 0,0:15:24.24,0:15:27.40,Default,,0000,0000,0000,,but loaded it with different load and
Dialogue: 0,0:15:27.40,0:15:31.04,Default,,0000,0000,0000,,this time the difference was much bigger
Dialogue: 0,0:15:31.04,0:15:33.56,Default,,0000,0000,0000,,this shows that the load on the Rope has

Dialogue: 0,0:16:00.60,0:16:02.68,Default,,0000,0000,0000,,recently there was a very interesting

Dialogue: 0,0:16:04.92,0:16:06.96,Default,,0000,0000,0000,,were cut and looked through the
Dialogue: 0,0:16:06.96,0:16:09.64,Default,,0000,0000,0000,,microscope and what they found was four
Dialogue: 0,0:16:09.64,0:16:12.48,Default,,0000,0000,0000,,dominating patterns the first one was a
Dialogue: 0,0:16:12.48,0:16:15.52,Default,,0000,0000,0000,,clean cut the second one was a tiered

Dialogue: 0,0:16:17.76,0:16:20.04,Default,,0000,0000,0000,,dual knife then they found some
Dialogue: 0,0:16:20.04,0:16:23.00,Default,,0000,0000,0000,,mushrooms these happened from high-speed
Dialogue: 0,0:16:23.00,0:16:27.52,Default,,0000,0000,0000,,fiber overload and lastly molten fibers
Dialogue: 0,0:16:27.52,0:16:29.44,Default,,0000,0000,0000,,and then we looked what p patterns they
Dialogue: 0,0:16:29.44,0:16:32.48,Default,,0000,0000,0000,,will find in ropes cut by different
Dialogue: 0,0:16:32.48,0:16:35.76,Default,,0000,0000,0000,,tests starting with ederly disc which
Dialogue: 0,0:16:35.76,0:16:39.16,Default,,0000,0000,0000,,produced a lot of Clean Cuts but also a
Dialogue: 0,0:16:39.16,0:16:41.72,Default,,0000,0000,0000,,lot of tiered Cuts this probably
Dialogue: 0,0:16:41.72,0:16:43.92,Default,,0000,0000,0000,,happened because the disc actually has
Dialogue: 0,0:16:43.92,0:16:47.32,Default,,0000,0000,0000,,these small teeth next they looked into
Dialogue: 0,0:16:47.32,0:16:50.12,Default,,0000,0000,0000,,the old mammut test and this one was
Dialogue: 0,0:16:50.12,0:16:52.92,Default,,0000,0000,0000,,pretty much dominated by mushrooms and
Dialogue: 0,0:16:52.92,0:16:55.12,Default,,0000,0000,0000,,the possible explanation is because the
Dialogue: 0,0:16:55.12,0:16:58.04,Default,,0000,0000,0000,,Rope was tensioned to unrealistically
Dialogue: 0,0:16:58.04,0:16:59.56,Default,,0000,0000,0000,,high Force
Dialogue: 0,0:16:59.56,0:17:01.24,Default,,0000,0000,0000,,and of course I had a question why
Dialogue: 0,0:17:01.24,0:17:03.76,Default,,0000,0000,0000,,didn't we use more realistic loads on
Dialogue: 0,0:17:03.76,0:17:06.72,Default,,0000,0000,0000,,this test when we lowered the preloading
Dialogue: 0,0:17:06.72,0:17:10.72,Default,,0000,0000,0000,,to 3 4 Kon then uh some of these ropes
Dialogue: 0,0:17:10.72,0:17:12.96,Default,,0000,0000,0000,,have not been able to be cut we were not
Dialogue: 0,0:17:12.96,0:17:14.44,Default,,0000,0000,0000,,able to compare the results you wanted
Dialogue: 0,0:17:14.44,0:17:16.56,Default,,0000,0000,0000,,that all the ropes will be cut but then
Dialogue: 0,0:17:16.56,0:17:18.40,Default,,0000,0000,0000,,you can measure how much it takes that
Dialogue: 0,0:17:18.40,0:17:20.76,Default,,0000,0000,0000,,was the difficulty of the test yeah okay
Dialogue: 0,0:17:20.76,0:17:24.00,Default,,0000,0000,0000,,next we looked into the old uiaa test
Dialogue: 0,0:17:24.00,0:17:26.84,Default,,0000,0000,0000,,and here we found a lot of mushrooms but
Dialogue: 0,0:17:26.84,0:17:29.56,Default,,0000,0000,0000,,also a lot of molten fiber
Dialogue: 0,0:17:29.56,0:17:32.20,Default,,0000,0000,0000,,and finally they simulated a realistic
Dialogue: 0,0:17:32.20,0:17:34.92,Default,,0000,0000,0000,,Dynamic scenario where the Rope was
Dialogue: 0,0:17:34.92,0:17:38.52,Default,,0000,0000,0000,,running across a sharp granite edge and
Dialogue: 0,0:17:38.52,0:17:40.40,Default,,0000,0000,0000,,also they compar the patterns in
Dialogue: 0,0:17:40.40,0:17:42.32,Default,,0000,0000,0000,,different parts of the Rope like The
Dialogue: 0,0:17:42.32,0:17:45.56,Default,,0000,0000,0000,,Shift versus the core and after all the
Dialogue: 0,0:17:45.56,0:17:48.88,Default,,0000,0000,0000,,analysis the study concluded that no
Dialogue: 0,0:17:48.88,0:17:51.44,Default,,0000,0000,0000,,test method can fully replicate the

Dialogue: 0,0:17:56.64,0:17:59.80,Default,,0000,0000,0000,,simulation so yeah a deep rap hole but
Dialogue: 0,0:17:59.80,0:18:03.64,Default,,0000,0000,0000,,this brings us to the best part of this
Dialogue: 0,0:18:03.64,0:18:06.56,Default,,0000,0000,0000,,video ah fancy this thing can go up and
Dialogue: 0,0:18:06.56,0:18:09.56,Default,,0000,0000,0000,,down yeah you don't like walking ladders
Dialogue: 0,0:18:09.56,0:18:11.32,Default,,0000,0000,0000,,so you made the machine which goes up
Dialogue: 0,0:18:11.32,0:18:15.56,Default,,0000,0000,0000,,and down Dano was climbing this Ladder
Dialogue: 0,0:18:15.56,0:18:18.76,Default,,0000,0000,0000,,Up and Down millions of times it kind of
Dialogue: 0,0:18:18.76,0:18:21.12,Default,,0000,0000,0000,,feels that it grabs the edge but it's
Dialogue: 0,0:18:21.12,0:18:24.96,Default,,0000,0000,0000,,not like super cut yeah I mean I
Dialogue: 0,0:18:24.96,0:18:27.80,Default,,0000,0000,0000,,wouldn't even think outside that this is
Dialogue: 0,0:18:27.80,0:18:30.64,Default,,0000,0000,0000,,an issue there sever edges out in the
Dialogue: 0,0:18:30.64,0:18:33.04,Default,,0000,0000,0000,,mountains that are much sharper than
Dialogue: 0,0:18:33.04,0:18:36.60,Default,,0000,0000,0000,,this yeah so if we do the tests then you
Dialogue: 0,0:18:36.60,0:18:38.92,Default,,0000,0000,0000,,will be afraid of climbing after
Dialogue: 0,0:18:38.92,0:18:42.96,Default,,0000,0000,0000,,it here you have this 45° surface so
Dialogue: 0,0:18:42.96,0:18:47.44,Default,,0000,0000,0000,,it's like 90° and then 45° cut yes cut
Dialogue: 0,0:18:47.44,0:18:50.16,Default,,0000,0000,0000,,yeah yeah so it's not actually like a
Dialogue: 0,0:18:50.16,0:18:53.20,Default,,0000,0000,0000,,pointy Edge it's relatively rounded Edge
Dialogue: 0,0:18:53.20,0:18:56.52,Default,,0000,0000,0000,,but the granite has this roughness to it
Dialogue: 0,0:18:56.52,0:18:59.48,Default,,0000,0000,0000,,yes I would say so let me get the reason
Dialogue: 0,0:18:59.48,0:19:01.72,Default,,0000,0000,0000,,we cannot make this standardized is
Dialogue: 0,0:19:01.72,0:19:03.36,Default,,0000,0000,0000,,because it's impossible to make this
Dialogue: 0,0:19:03.36,0:19:07.36,Default,,0000,0000,0000,,granite edge standard like yeah so this
Dialogue: 0,0:19:07.36,0:19:09.68,Default,,0000,0000,0000,,test setup is not something that aims to
Dialogue: 0,0:19:09.68,0:19:11.76,Default,,0000,0000,0000,,be a standardized test method that needs
Dialogue: 0,0:19:11.76,0:19:14.08,Default,,0000,0000,0000,,to be reproducible in different places
Dialogue: 0,0:19:14.08,0:19:17.60,Default,,0000,0000,0000,,so you need that exact same granite edge
Dialogue: 0,0:19:17.60,0:19:19.76,Default,,0000,0000,0000,,at in 10 different places this was not

Dialogue: 0,0:20:13.00,0:20:15.68,Default,,0000,0000,0000,,on yeah but it's just being pulled out
Dialogue: 0,0:20:15.68,0:20:17.96,Default,,0000,0000,0000,,it's not holding anymore huh so you can

Dialogue: 0,0:23:58.44,0:24:02.44,Default,,0000,0000,0000,,and this rope has one more sheath you
Dialogue: 0,0:24:02.44,0:24:04.80,Default,,0000,0000,0000,,can say this intermediate sheath is made

Dialogue: 0,0:24:29.68,0:24:32.40,Default,,0000,0000,0000,,stiff so to solve this they needed to

Dialogue: 0,0:24:50.08,0:24:54.40,Default,,0000,0000,0000,,arite it's a hybrid yes okay and you see
Dialogue: 0,0:24:54.40,0:24:56.72,Default,,0000,0000,0000,,that there is one with a longer yarn
Dialogue: 0,0:24:56.72,0:25:00.76,Default,,0000,0000,0000,,inside yeah and one is sh okay so there
Dialogue: 0,0:25:00.76,0:25:04.56,Default,,0000,0000,0000,,is two Thin strings one is completely
Dialogue: 0,0:25:04.56,0:25:07.24,Default,,0000,0000,0000,,stretched now and the other one is

Dialogue: 0,0:25:09.84,0:25:11.72,Default,,0000,0000,0000,,is the one with the over length if you
Dialogue: 0,0:25:11.72,0:25:13.12,Default,,0000,0000,0000,,load it
Dialogue: 0,0:25:13.12,0:25:15.40,Default,,0000,0000,0000,,now you do not

Dialogue: 0,0:25:24.72,0:25:28.36,Default,,0000,0000,0000,,yarn without an overlength so not good
Dialogue: 0,0:25:28.36,0:25:31.52,Default,,0000,0000,0000,,good but by introducing an overlength in
Dialogue: 0,0:25:31.52,0:25:34.16,Default,,0000,0000,0000,,aramite they managed to achieve a curve
Dialogue: 0,0:25:34.16,0:25:37.32,Default,,0000,0000,0000,,like this so basically during the fall

Dialogue: 0,0:25:39.76,0:25:43.84,Default,,0000,0000,0000,,any difference on this rope no nice and
Dialogue: 0,0:25:43.84,0:25:46.20,Default,,0000,0000,0000,,why is it hybrid inside why is it not
Dialogue: 0,0:25:46.20,0:25:50.20,Default,,0000,0000,0000,,all armed it will not um be held in
Dialogue: 0,0:25:50.20,0:25:53.40,Default,,0000,0000,0000,,position so you need anara because it
Dialogue: 0,0:25:53.40,0:25:55.76,Default,,0000,0000,0000,,you have the overlength anywhere and if
Dialogue: 0,0:25:55.76,0:25:58.80,Default,,0000,0000,0000,,you move with the Rope
Dialogue: 0,0:25:58.80,0:26:02.20,Default,,0000,0000,0000,,the maybe it changes the place that's a
Dialogue: 0,0:26:02.20,0:26:04.68,Default,,0000,0000,0000,,very smart design now it makes more
Dialogue: 0,0:26:04.68,0:26:08.04,Default,,0000,0000,0000,,sense how does it come back after load
Dialogue: 0,0:26:08.04,0:26:10.12,Default,,0000,0000,0000,,cuz otherwise you would stretch and then
Dialogue: 0,0:26:10.12,0:26:12.32,Default,,0000,0000,0000,,the middle layer would move somewhere
Dialogue: 0,0:26:12.32,0:26:14.56,Default,,0000,0000,0000,,but since you have some nylon in it it
Dialogue: 0,0:26:14.56,0:26:16.88,Default,,0000,0000,0000,,will reset the middle layer probably as
Dialogue: 0,0:26:16.88,0:26:20.20,Default,,0000,0000,0000,,well yes of course mhm now as a fun fact
Dialogue: 0,0:26:20.20,0:26:23.48,Default,,0000,0000,0000,,this robe has only 4% of its weight in

Dialogue: 0,0:27:23.40,0:27:26.12,Default,,0000,0000,0000,,a tiny bit Yeah so while this middle
Dialogue: 0,0:27:26.12,0:27:28.48,Default,,0000,0000,0000,,layer was adding extra protection for
Dialogue: 0,0:27:28.48,0:27:32.60,Default,,0000,0000,0000,,the Rope it was still eventually cut

Dialogue: 0,0:27:43.16,0:27:45.80,Default,,0000,0000,0000,,go it's about does it hold in this
Dialogue: 0,0:27:45.80,0:27:48.36,Default,,0000,0000,0000,,scenario or not mhm so we are kind of
Dialogue: 0,0:27:48.36,0:27:51.00,Default,,0000,0000,0000,,deducting from this test setup that it
Dialogue: 0,0:27:51.00,0:27:54.32,Default,,0000,0000,0000,,does perform significantly better than

Dialogue: 0,0:27:56.48,0:27:59.76,Default,,0000,0000,0000,,diameter so if you look in keeping the
Dialogue: 0,0:27:59.76,0:28:03.16,Default,,0000,0000,0000,,same weight of the rope and same handle
Dialogue: 0,0:28:03.16,0:28:05.36,Default,,0000,0000,0000,,you will get an extra safety margin on

Dialogue: 0,0:28:06.92,0:28:08.60,Default,,0000,0000,0000,,need to be aware of just because you
Dialogue: 0,0:28:08.60,0:28:11.36,Default,,0000,0000,0000,,have an extra safety margin doesn't mean
Dialogue: 0,0:28:11.36,0:28:15.60,Default,,0000,0000,0000,,it will absolutely not break this is
Dialogue: 0,0:28:15.60,0:28:20.48,Default,,0000,0000,0000,,no so a very interesting design indeed

Dialogue: 0,0:28:25.16,0:28:27.80,Default,,0000,0000,0000,,layer there was something that had

Dialogue: 0,0:28:30.48,0:28:33.04,Default,,0000,0000,0000,,resistance so instead of having the Rope
Dialogue: 0,0:28:33.04,0:28:35.40,Default,,0000,0000,0000,,safely attached to the beam I came up
Dialogue: 0,0:28:35.40,0:28:38.32,Default,,0000,0000,0000,,with a brilliant idea to attach it to

Dialogue: 0,0:28:40.56,0:28:43.16,Default,,0000,0000,0000,,break when I will be L yeah no I think
Dialogue: 0,0:28:43.16,0:28:46.88,Default,,0000,0000,0000,,um it won't yeah because Dynamics also
Dialogue: 0,0:28:46.88,0:28:49.48,Default,,0000,0000,0000,,play a big role so but let's say I I
Dialogue: 0,0:28:49.48,0:28:52.64,Default,,0000,0000,0000,,panic as a bler and I take really hard
Dialogue: 0,0:28:52.64,0:28:55.68,Default,,0000,0000,0000,,will it break that we will find
Dialogue: 0,0:28:55.68,0:28:59.08,Default,,0000,0000,0000,,out so let's say
Dialogue: 0,0:28:59.08,0:29:01.96,Default,,0000,0000,0000,,what I'm afraid is that I will jump and
Dialogue: 0,0:29:01.96,0:29:03.96,Default,,0000,0000,0000,,I will end up there and then it will
Dialogue: 0,0:29:03.96,0:29:06.72,Default,,0000,0000,0000,,break and I will fall yeah that would

Dialogue: 0,0:29:30.44,0:29:33.08,Default,,0000,0000,0000,,so my plan was to take during the fall
Dialogue: 0,0:29:33.08,0:29:35.68,Default,,0000,0000,0000,,and at the same time go down to cause as
Dialogue: 0,0:29:35.68,0:29:38.60,Default,,0000,0000,0000,,hard catch as possible however since I

Dialogue: 0,0:30:04.56,0:30:08.52,Default,,0000,0000,0000,,2.98 so almost 3 kons in our previous
