Yeah I was thinking the brilliant sponsorship was more of a main channel thing and this seemed like a zachstar himself type of video. Hope the reason they removed it wasn't me trolling about you being political on this channel.

[@TheDarklink82]

To be fair to the actual design engineer on the titan sub, he actually did raise objections to the design of the sub as he believed that it wasn't safe to use....he was fired because of it.

[@theastuteangler]

Which further solidifies that this was not a "tragedy", this was deliberate stupidity and rich-people hubris. Brilliant can suck a lemon for their political-correctness or whatever they wanna call it.

[@beskamir5977]

Yeah, I was kind of hoping Zack would mock that by having the engineer get immediately fired after raising several concerns.

[@codyrodriguez1056]

And to be fair it’s not a bad sub, if your just doing swallow dives. But to take twice it’s limit is just retarded

[@extropiantranshuman]

@@beskamir5977 I could only imagine the engineer talking about advanced physics and people look at them like it's over their head - and then shoos the person to get out without telling them and if questioned would say 'eh (whispers how the engineer had their own ideas) - they didn't focused on what we want to look after: the submarine. Then someone else says 'you mean submersible' and then the one who said submarine says 'it fins in the back to look like a fish. See this is what we're bring to the depths'. Then the person who looks at it gets in awe and knows what's next: to buy a video game controller. There everyone - I wrote it out to enjoy.

"what is the pressure gonna be down there" "force over area" GOLDEN

[@michaelvalentine2821]

Same as up here!

[@lucykitsune4619]

Well I mean it's not entirely wrong, it's just that the force of the water pusing onto the area is a LOT bigger and generally everything in the integral cancels out so you're better off just calculating hydrostatic pressure...

[@mahpell7173]

r/technicallycorrect

[@lostboy8084]

Well technically the closer you get to the Earth's core the more gravity will effect you and things around you. So the deeper you go underwater the more gravity stronger gravities force. Meaning water pressure even the air pressure in the sub and yourself will be affected (only slightly as the sub bears the brunt of the pressure from the water and gravity) but most people would think water pressure and forget gravitational force

[@junkster777]

[@guillaumedupuis4929]

My only question is why did they not implement a fast travel option to teleport to the titanic

[@extropiantranshuman]

too bad they just didn't market VR (virtual reality) instead.

[@magmaman8021]

because you need to discover the area before you can fast travel to it, that's why they were traveling there, to unlock it for fast travel

[@bipolar-tiger]

Because you can't fast travel when there are enemies around.

[@subjekt5577]

I mean technically speaking, they did..... The less buoyant, the faster the dive rate, and displacing all that air in the submersible with seawater definitely decreased the buoyancy

In my opinion, the amount of grief time increases with how much the victims suffered. And how - numerous - young - marginalized - culturally similar to yourself they are.

[@doncarlodivargas5497]

Did they not have audible monitoring system to do exactly that, detecting sound? And the monitoring system was indicated "red"?

Does the controller have vibration? Yes? Ok, have that trigger if the walls or window are about to implode do to too much stress.

[@extropiantranshuman]

The vibrations are also in the submersible to make you feel the world around you (like when you bump into something in a video game) for a first-hand experience! Create the thrills of the scene for a real adventure - and build a points system so that if you have enough hits to the world around you - you lose and can reset from the starting point on the ocean surface to start over the process again.

[@extropiantranshuman]

@@kekistaniattackhelicopter2242 ah yes - because the video game controller didn't get ripped to shreds like the capsule did - it's the part that made the most sense of it all. Well that's true - it's the only thing that's left standing and surviving at the end of all this. It does make sense that it's the most sensical part, even if it led the capsule to its fate - because it didn't itself get destroyed in the process. I can only imagine the engineers using that logic at the time.

It seems that online courses are not enough to learn how to build a submarine.

"It only echos if its strong" This scares me.... because it sounds like something someone would actually say. So I fear this is a direct referance to something rather than just a joke.

[@jblock9675]

i think it might kinda be, the way they were measuring the damage and like tiny internal cracks in the hull was, if i'm not mistaken, a system that recorded audio and listened for something that would indicate stress on the hull, but for some reason (not engineer, just saw a video with cool graphs) that only really works with metals, with composites it won't really be useful. (someone please correct me)

[@ZM1306]

@jblock9675 It works for metal because when you know the composition, you know what its yield curve is, and it will start to yield before it fails. That is very diffrent from banging on it and saying "it echos so it's good!" That scares me.

​@@MrA6060game controllers are not precise, it's the whole reason nicer aftermarket controllers exist. The switch for example suffers large amounts of drift after a short time, while even $1 joystick modules might last longer. What you want at minimum is hall effect gimbals, or even the $40 hobby RC controller I have has more precision (but many still upgrade to nicer hall effect gimbals in it too). I'm not saying you need a $10k controller to safely operate remote control planes, but I've used one (still hobby grade, not milspec), but interestingly it's very difficult to find controllers the military will allow even for testing only for small UAVs (because they don't want Chinese parts in them, or at least minimal) and not so much with quality concerns.

[@jakegarrett8109]

@@MrA6060 Its a difference in quality though, and at some point its nicer than what the military has. Military spec means I've specified a material, heat treatment, and coatings, but my design may still suck and be insufficient. It also means its made by the lowest bidder. Meanwhile I've got a MUCH more precise pair of headphones for audio quality than military spec (because I can spend money on perfection, whereas in the military you don't care if Beethoven is slightly off, you just need to listen to someone on a staticky radio). But yes the part I was just designing while you typed this comment is probably more over-designed and analyzed than some parts of that sub. I'm an aerospace and mechanical engineer, and for my own personal projects I don't have time constraints, I don't have penny pinching managers, I do whatever I want so my stuff is often WAY nicer than anything on the market (maybe expensive if I were to sell, but man is it nice!).
