Dialogue: 0,0:16:12.92,0:16:16.08,Default,,0000,0000,0000,,rate so next a set that we dropped from

Dialogue: 0,0:16:37.96,0:16:41.92,Default,,0000,0000,0000,,22.3 23 23 so basically dropping from

Dialogue: 0,0:16:48.20,0:16:51.44,Default,,0000,0000,0000,,but so we broke all the samples and
Dialogue: 0,0:16:51.44,0:16:54.36,Default,,0000,0000,0000,,again all of them broke above their
Dialogue: 0,0:16:54.36,0:16:57.76,Default,,0000,0000,0000,,rating and ironically some samples were

Dialogue: 0,0:17:12.64,0:17:15.32,Default,,0000,0000,0000,,impact on ah so you say that there are
Dialogue: 0,0:17:15.32,0:17:17.88,Default,,0000,0000,0000,,parts of Carabiner that are more
Dialogue: 0,0:17:17.88,0:17:19.92,Default,,0000,0000,0000,,susceptible to breaking and if you have
Dialogue: 0,0:17:19.92,0:17:22.52,Default,,0000,0000,0000,,a Nick in those parts it's more
Dialogue: 0,0:17:22.52,0:17:26.60,Default,,0000,0000,0000,,problematic yes we break either here or
Dialogue: 0,0:17:26.60,0:17:29.92,Default,,0000,0000,0000,,here yeah so if I would have have a Nick

Dialogue: 0,0:17:32.28,0:17:34.96,Default,,0000,0000,0000,,would be more problematic yes so now we

Dialogue: 0,0:21:50.52,0:21:53.36,Default,,0000,0000,0000,,and observe the elongation so now we
Dialogue: 0,0:21:53.36,0:21:56.96,Default,,0000,0000,0000,,pulled to 9 kons and then we relaxed
Dialogue: 0,0:21:56.96,0:21:59.60,Default,,0000,0000,0000,,down and it came back to exactly what it
Dialogue: 0,0:21:59.60,0:22:01.32,Default,,0000,0000,0000,,was before yeah so now we're going to
Dialogue: 0,0:22:01.32,0:22:05.00,Default,,0000,0000,0000,,try to pull to 10 and see to 11 to 12

Dialogue: 0,0:22:12.84,0:22:15.88,Default,,0000,0000,0000,,and here are the observations at around

Dialogue: 0,0:22:26.48,0:22:28.80,Default,,0000,0000,0000,,going to notice however that changes is
Dialogue: 0,0:22:28.80,0:22:31.88,Default,,0000,0000,0000,,quick with higher forces at 70% of the
Dialogue: 0,0:22:31.88,0:22:34.44,Default,,0000,0000,0000,,rating the formation is already about
Dialogue: 0,0:22:34.44,0:22:37.24,Default,,0000,0000,0000,,half a millimeter which is significant
Dialogue: 0,0:22:37.24,0:22:39.84,Default,,0000,0000,0000,,and pulling to even higher forces
Dialogue: 0,0:22:39.84,0:22:43.72,Default,,0000,0000,0000,,Carabiner becomes very plastic mm
Dialogue: 0,0:22:43.72,0:22:48.24,Default,,0000,0000,0000,,already it's elongated for 9 something

Dialogue: 0,0:22:54.24,0:22:56.60,Default,,0000,0000,0000,,breaking maybe like
Dialogue: 0,0:22:56.60,0:23:00.52,Default,,0000,0000,0000,,this yeah this one is like full CM

Dialogue: 0,0:23:03.48,0:23:07.04,Default,,0000,0000,0000,,you stay below 10 Kon it would always go

Dialogue: 0,0:23:09.08,0:23:11.60,Default,,0000,0000,0000,,problem so of course I got curious what
Dialogue: 0,0:23:11.60,0:23:15.04,Default,,0000,0000,0000,,happens if you repeatedly load above 10
Dialogue: 0,0:23:15.04,0:23:17.36,Default,,0000,0000,0000,,K yeah now we're going to pull on the

Dialogue: 0,0:23:25.44,0:23:27.96,Default,,0000,0000,0000,,while so after the first pull the
Dialogue: 0,0:23:27.96,0:23:31.00,Default,,0000,0000,0000,,carabiner had almost half a MM of
Dialogue: 0,0:23:31.00,0:23:33.44,Default,,0000,0000,0000,,permanent deformation and then repeated
Dialogue: 0,0:23:33.44,0:23:36.84,Default,,0000,0000,0000,,pulls we're slightly growing that but
Dialogue: 0,0:23:36.84,0:23:40.04,Default,,0000,0000,0000,,less and less on every extra pull
Dialogue: 0,0:23:40.04,0:23:42.44,Default,,0000,0000,0000,,however this is the behavior on the
Dialogue: 0,0:23:42.44,0:23:45.00,Default,,0000,0000,0000,,relaxed state of the Carabiner when it's
Dialogue: 0,0:23:45.00,0:23:47.60,Default,,0000,0000,0000,,not under load anymore if we look at the
Dialogue: 0,0:23:47.60,0:23:49.72,Default,,0000,0000,0000,,top of the chart where we can see
Dialogue: 0,0:23:49.72,0:23:52.56,Default,,0000,0000,0000,,elongation under load it is much more
Dialogue: 0,0:23:52.56,0:23:54.76,Default,,0000,0000,0000,,interesting for the first Cycles
Dialogue: 0,0:23:54.76,0:23:58.64,Default,,0000,0000,0000,,elongation keeps growing as well however
Dialogue: 0,0:23:58.64,0:24:01.32,Default,,0000,0000,0000,,later it starts shrinking and this is
Dialogue: 0,0:24:01.32,0:24:04.28,Default,,0000,0000,0000,,due to work hardening Where Metal
Dialogue: 0,0:24:04.28,0:24:07.92,Default,,0000,0000,0000,,becomes stronger and harder but less
Dialogue: 0,0:24:07.92,0:24:11.12,Default,,0000,0000,0000,,ductile now in theory work hardening
Dialogue: 0,0:24:11.12,0:24:13.40,Default,,0000,0000,0000,,could lead to stress cracking and
Dialogue: 0,0:24:13.40,0:24:16.32,Default,,0000,0000,0000,,compromised strength so to test this we
Dialogue: 0,0:24:16.32,0:24:18.96,Default,,0000,0000,0000,,pull this Carabiner till failure while
Dialogue: 0,0:24:18.96,0:24:21.44,Default,,0000,0000,0000,,normal elongation curve of the Carabiner
Dialogue: 0,0:24:21.44,0:24:24.32,Default,,0000,0000,0000,,would look like this after the hardening
Dialogue: 0,0:24:24.32,0:24:27.48,Default,,0000,0000,0000,,Cycles there was a new elastic limit and
Dialogue: 0,0:24:27.48,0:24:29.92,Default,,0000,0000,0000,,it took more Force to deform the
Dialogue: 0,0:24:29.92,0:24:33.32,Default,,0000,0000,0000,,Carabiner further however that had no

Dialogue: 0,0:24:36.36,0:24:38.80,Default,,0000,0000,0000,,strength now of course in real life
Dialogue: 0,0:24:38.80,0:24:41.20,Default,,0000,0000,0000,,climbing situations we would never reach
Dialogue: 0,0:24:41.20,0:24:44.68,Default,,0000,0000,0000,,those forces or that many cycles so it's
Dialogue: 0,0:24:44.68,0:24:46.76,Default,,0000,0000,0000,,really nice to know that there is such a
Dialogue: 0,0:24:46.76,0:24:49.12,Default,,0000,0000,0000,,huge safety margin but in case you're
Dialogue: 0,0:24:49.12,0:24:51.56,Default,,0000,0000,0000,,rigging something where High forces are
Dialogue: 0,0:24:51.56,0:24:54.44,Default,,0000,0000,0000,,possible then keep in mind that our
Dialogue: 0,0:24:54.44,0:24:57.08,Default,,0000,0000,0000,,investigation just scratched the surface
Dialogue: 0,0:24:57.08,0:25:00.64,Default,,0000,0000,0000,,also 50% of elastic limit or yield limit
Dialogue: 0,0:25:00.64,0:25:04.12,Default,,0000,0000,0000,,that we found is for this Carabiner if
Dialogue: 0,0:25:04.12,0:25:06.92,Default,,0000,0000,0000,,we would change the shape of it or maybe
