I find carbon fiber to be inferior to metals. In a very primitive example on a golf club shaft one tiny nick in the carbon shaft will critically weaken it. With a steel shaft you can ding it scratch it and it still holds up. Carbon shafts will fail at the flaw its only a matter of time before something you do in your swing to impact and it shatters. The devil is in the detail. Primative explanation but I have seen how bad carbon fiber fails far before a metal shaft.

@warbydeception3228 Says:
Giant pressures compress the CF hull more than the titanium which, over cycles, completely breaks the small, hand-applied glue joint resulting in a catastrophic failure that shreds the CF in an instant. Putting aside the nonlinear anisotropic behavior of composites like CF, the glue joint was the most criminal part of the design. GLUE? Applied over a small surface area by hand?? How could any confidence be assumed in that design/assembly process? I’d never approve that design for production.
@warbydeception3228 Says:
Ever see that picture of everyone who worked on the sub posing in front of it? How the HELL did any of those engineers feel comfortable with the design after taking even one material science class? I know they took it. They should know how brittle materials like carbon fiber fracture, and that hand-gluing it to titanium is unreliable and prone to de-adhering when parts compress… I’d never stay on this job if I knew this was the final design. I’d be warning people to stay the hell away! And I’d love to see the simulations they did (if any) because their assumptions must have been horribly off.

I went the estate sale of Paul-Henri Nargeolet and bought a bunch of cool loot. Apparently his wife and family didn’t want everything in the home. It was very interesting to say the least.
@TomNimmo Says:
This makes perfect since, the Titan was having problems surfacing, we all heard that part when they had only went up like 25 meters in 30 minutes after first dropping the ballast and doing everything they could to go up. They knew they were screwed there, they had already taken on water. This guy nailed it, the best explanation I've heard. I thought I had it figured out but I didn't. most of us probably knew it was in the joint between the carbon fiber and titanium... well I guess this was close to what I was thinking but this just clarified everything. This is the smartest guy I've seen on YT, I'm gonna check out his other content
@torben777 Says:
The problem with your analysis is that the main hull was made of carbon fibre. Carbon fibre has a tendency to scatter like glass if pushed past the breaking point.
It is thus very likely that the animation is closer to the truth than your pinhole theory.
There are some pretty good simulations out there based on exact models of the sub with actual materials and construction methods.

I see you for what you do now. you take the bullshit out of sensational stories and show us the reality of these things. I can respect that
@NeedlessPedantics Says:
Thunderfoot,
In your comparison of the bulk modulus of Titanium, and carbon fibre laminate you mixed up the units by comparing imperial units to SI units. Both materials have a bulk modulus of 130< Gpa, or 18.8< Msi. They have nearly identical ratings.
Apologies if this has already been addressed, but you should make a correction.
Thanks for the videos.
@jasonkristian8457 Says:
are you for real, if you have pin whole at that deapth it would cut through the other side but even before that happened the pressure would just impolde the sub
@andromedach Says:
TIL there is an english voice over version of Das Boot.
@GertKlimanschewski Says:
Sorry..... I can't follow you....?
An implosion in this case is the most believable....!
Anyway nobody has seen it...!
A plausible guess is, it cracked along the titanium and carbon and imploded.... No signs it was flooded.... It would be in one piece on the ground.
BUT.... they found only debris of carbon and the intact pieces of titanium so far I've heard.
I like your channel but sometimes....?
FACTS ARE FACTS.... and here are no facts left.... The most is speculation, but IMPLOSION seems most believable 😱🤢
@user-uz1yv2oc9v Says:
The main reason your experiment failed with the pressure washer is that most home pressure washers use scam-like marketing with their sales figures.. the 125 bar pressure advertised is just peak pressure and not sustained pressure. I have a commercial diesel engine powered pressure washer that can provide sustained pressures and it would destroy that plastic plate
@nealb6974 Says:
One thing I don't understand is how you say the water jet from the pinhole leak caused the sub to fall apart. If there was a pinhole leak I'd think the sub would sink and stay relatively intact, but the recovered wreckage shows a completely destroyed sub.

I like how the fox animation has a fireball underwater
@JohnnyWolfblood Says:
It failed because it was piece of shit made from literal garbage.
Instead of rambling on and on about water pressure, you could have given us 100 times more information by spending 30 seconds just zooming in on the masking tape and cheap scrap metal.
Why does this video need to be half an hour long?
@JohnnyWolfblood Says:
Or is it perhaps because it was made out of literal fucking tape, cheap scrap metal and xbox controllers?
@pauldziejman Says:
If you watch Das Boot, you MUST watch it in the original German. The English dub dosent do it justice. Just read the subtitles
@arposkraft3616 Says:
Titan titanic, i think fault is i naming
@TheDZHEX Says:
I think one of the hydraulic press channels actually reproduced this - they increased pressure, nothing remarkable happened, but when they opened the container, they found that the sub model was full of water, without any significant signs of damage.

@damon1957ful Says:
Water as all ways been know to compress, just remmeber water getting in to brake system being spongy also air has the same effect and the compressablity of water, so which idiot said its not needs shooting
@CainXVII Says:
That glass demonstration was great.
@tommymac3029 Says:
I think your demo with the pressure washer didn't go as expected is because the nozzle was not fixed at 90 degrees to the plastic surface. The angle of deflection dissipated energy in the water stream. If you used a fixture like the type used for portable drills for drilling 90 degree holes, it might have worked to hold the nozzle steady and in a single location, much like the way the water jet cutter works.
@Whyusemyname Says:
I think your thesis about the pinhole leak is incorrect. They found the sub smashed to pieces. That would imply an implosion and not the sub filling up with water, which would have equalize the pressure and kept it all in one piece.
@SteveSnowman Says:
Excellent. Thanks.

@bewing77 Says:
While I agree that "dad Boot" is a great movie, it really isn't pronounced like the English word boot, as in something you wear on your foot.. the double "oo" becomes more like an "oe" sound, or "Å" in Swedish and Finnish. So the correct pronunciation is more like you pronounce "bought" in English. Just to be an annoying stickler 😂

@rhobot75 Says:
Interesting. I quit smoking cigarettes just over 12 years ago. I will sometimes use the idea of being in a submarine or as here submersible to describe what will happen if I have even 1 puff. 1 puff and my quit is done. The submersible that is my precious quit will get a pinhole and I will drown, it might be two hours it might be two months but I will be back smoking and probably more than ever. Although now I suppose I have to say I'll be sawed through and I won't be watching the sub fill with water at all, I'll be dead pretty much immediately, equating to I will instead be magically teleported to the store and instantly smoking several cartons simultaneously, no coy dancing around will I won't I. It's a whole new way to visualize relapse!
And I realize now I will have to find another way to describe it, maybe I can't anymore be deep under water in a sub, I have to be standing next to the wall of a damn and there's now a hole in it and depending on placement of this hole I will be back drowning in addiction soon. Anyway! Interesting reality check on my idea. Though I do still like it. Cheers!
@davidseed2939 Says:
you need a pressure gauge on your lance. Dont forget that the pressure and velocity obtained will be limitd by the maximum power of the pump.
power = pAv
@Kloppin4H0rses Says:
You are WAY WAY WAY over embellishing the vocabulary you are using to describe implosion and it doesn't make you seem smart. Especially when it makes you miss the mark entirely.
The reason fish and marine mammals don't die at depth is because the pressure is equalized between the immense pressure inside and outside their body. So the net force pressing on them is essentially zero.
The ship was being maintained at a pressure of 1 atm~. Meaning that there was an immense difference between the pressure outside and inside the sub. The only thing holding the pressure out was the material strength of the carbon fiber. That is until it didn't hold anymore. And the ship crunched like aluminum can in the hands of an alcoholic who just finished it.
Any discussion beyond this point should be centered around the strength of the carbon fiber. Not the compressibility of water.

What really did it was hubris. It killed the titanic, it killed the titan.
@becksy539 Says:
I think the endless cycling of the carbon fibre might have also paid a part, wonder if they have performed any small scale fatigue tests on the material to at least attempt to calculate how many dives it would survive
@aircraftcarrierwo-class Says:
It failed because carbon fiber is useless at resisting compression forces. This is not a mystery.
The porthole only being rated for less than 1/3rd of their dive's depth definitely didn't help.
But the biggest culprit is the hull material being useless. Only the epoxy resin was resisting the ocean. The fiber contributed nothing, and repeated dives weakened the resin each time. It is well documented that Oceangate did no testing or maintenance on the submersible.
@cmillerg6306 Says:
Did you have a comment on the acoustic events that some ascribed to an implosion?
