When you're an engineer for the Titan submersible 

Yeah, because video is kinda in poor taste regardless if the subject was of questionable engineering.

@@sgstudioofficialwomp womp

Inconceivable!

Was the sponsor like, new to Zach Star videos or something? Cowards!

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.

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.

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

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

and the replacements were all diversity hires.

@@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.

Same as up here!

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...

r/technicallycorrect

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

​@@lostboy8084wrong, gravity weakens the further down you go. There's deep mine shafts you can go down and when you weight yourself, it's actually lower than if you were on the surface.

Almost ™️

honestly L should've just aerialed than than did a speedflipped on the surface

@@TheEntity.Stories From Smash to Rocket League lmao

8-bit theater fighter blocked the ground when they were falling to their deaths. Saved his whole party.

Which is weird, because I thought that was what the manual said that you had to do, to fly.

Joycon is a hundred times better quality than what they used.

idk if you intentionally made that perfect pun but i'm impressed nonetheless

@@EMETRLno way it wasn’t intentional I say

Haha. Driff pun. 🤣🤣

​@@illustriouschinnah

Do you remember the last time you saw 2 people in this channel?, Although the idea itself is good, here you would see him with an "engineer #1" written in a piece of paper in the shirt, then #2, #3, etc. Hope he does that if there is anything extra about that piece of evidence.

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

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

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

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

Dude it would ruin the difficulty of the game. You gotta earn your way there to get the true gaming experience.

Likee😂😂😂

I wonder if the company stole parts from McDonald's to build the sub, hence the broken ice cream machines 🤔

@@MrKabobCK We might be onto something here. We finally figured it out boys

At least the McDonald's ice cream machines are still ice cream machines unlike the TITAN which is now a pile of scrap metal at the bottom of the ocean 😶.

*was*

Funny enough those ice cream machines wouldn't be broken so often if they weren't coded to be that way by the manufacturer.

Besides, Stockton Rush was basically asking to become OceanPâté the moment he set foot in that death trap

I think you just said big words and hoped they would make sense and go together. But how else are we supposed to know this is a legit review of something sciencey.

tell that to the dead kids mom.

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. You may disagree on a few of the criteria, but it won't change the fact that the Titan disaster was fair game *minutes* after it happened. The one overconfident wannabe Tony Stark checks only the last box, and a handful of millionaires are none of these.

Titan got 2 stocked by the North Atlantic

@@SubSilence Zero to death.

Nah. Mortal Dive. "Finish It". "Multiple Fatalities." "Sub-zero Depth wins."

That'd be epic. Real Engineering and Thunderfoot already did their part in breaking down what happened but it'd be neat to hear Zach's perspective too.

I mean... Thunderfoot did

Zach's an electrical engineer

In depth you say? 😆

idk I mean personally I think the fact that they used a wireless 2005 gameboy controller or whatever to pilot this thing pretty much demonstrates how much they care about safety just in and of itself

I know what you mean.

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)

@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.

@@ZM1306 Thanks! needed to look up what a yield curve was but it's cool such a method would work at all, I'll keep that in mind next time I build a submarine for visiting the titanic

@jblock9675 Lol, I wasn't even worried about it with my sub project. Being I want to just putt around in my local lakes. But every time you tighten and torque a bolt the same principal applies. I had to look up the correct name, it is the stress-strain curve.

@@ZM1306 oh cool, ur making a sub? How large?

Congratulations you just won the internet!🤣🤣🤣🤣🤣

They could hear the hull cracking for over almost an hour apparently.

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

So the "engineering" in this video is actually more sound than the real deal. Oh boy

​@@doncarlodivargas5497 Ive seen the audible monitoring system compared to a flash detector to warn of thunder. Sure the light gets there first. But not far enough ahead to do anything about what's coming.

@@BadOompaloompa79 - the initial comment was the audible system of knocking on the hull, how far ahead will that detect a failing hull?

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 Right, so they can anticipate the impending implosion and really FEEL the excitement!

Unironically the controller was the only thing that made sense in this craft. Anyone who had a game console knows how much abuse those things can take before you really have to replace it.

@@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.

The problem isn't that they used a video game controller. That's quite common. Nicely ergonomic, most people are used to using them, designed to be easy to use. The problem is they used a cheap one that has a reputation for being iffy. And it was a wireless connection, instead of wired. And they didn't bring a spare. They cheaped out, even on the damn controller!

@@samuelmellars7855 Also, the controller was not the only thing that could operate the sub. The main controller was the laptop.

What rock do you live under???

​@@samuelmellars7855 For context, the BILLIONAIRES cheaped out on a 60 dollar controller. Let that Sink In.

@@anders6326 millions on the sub and bucks on the controller. What could possibly go wro IMPLODES.

ocw and mooc's are to help with self-learning to be able to step foot in a class setting, not replace the class itself.

we need engineering humor. Really!

He actually has a second channel Zach Star Himself just dedicated to comedy skits.

@@meapyboy12345 I didn't realize I WASN'T on Zach Star Himself until I read this! I forgot he has two channels.

the controller part is not actually the problem, like that was the smart decision, controllers are made to last and to work very precisely believe it or not. It's the rest that was the actual problem

I know if I had a company - I'd advertise hard in this video! The more we make stupidity foolish - the better. The fact that brilliant is marketed on brilliance - seems counterpoint to turn down this opportunity!

​@@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 after market controllers are still game controllers. Also you gotta see the whole thing. Using a controller was probably their smartest choice considering everything else they vhose

@@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!).

and I'm glad he did. This is getting to the real stuff. I wish there was an entire channel dedicated to satirize engineering disasters. It would make learning about them so much easier!

@@extropiantranshuman I agree.
