What did the Carbon Fibre Sub say to the Titanium Sub?

I’m Crushed.

[Round Earther]

That’s the terror of knowing
What this world is about
Watching some good friends screaming
“Let me out!”

[Libloather]

“Is that a leak?”

[Fester Chugabrew]

I wonder if we will ever know how deep the Titan was when it imploded.

[griffin]

If you want to imagine what an implosion is like at 12,000 ft below sea level, stuff 5 hamsters in a Pepsi can and run it over at 60 miles an hour.

Was doing some rough math calculations. Say an automobile tire is filled to 30 psi. If the Titanic ocean floor is stated correctly at 6000 psi it would be the equivalent pressure of 200 tires combined. Quite a blowout or blow in.

Give it a few years.

I suspect you’ll start hearing about “unexpected” airframe failures in aircraft.

I suspect it will happen eventually. Just when is the question?

And the beauty of composites like this is that they give you little to no prior warning unlike metal.

I presume that’s MJ (MegaJoules), not mJ (milliJoules)

[BitWielder1]

Granite weights about 2.7 times the same volume of water.
Imagine a Granite Obelisk 2900 feet tall.
(The Washington Monument is 554 feet tall and it's hollow.)
That's how crushed they were.

Now for a more interesting question, how can we be sure that there was anyone on board?
Maybe these people wished to "disappear" for some reason.
They were all wealthy enough to charter from a more reputable firm.

“A “live” rant about carbon fiber submarines”

I’ll skip the pun out of good taste

[Leaning Right]

> The amount of energy contained in one kilogram of TNT is given (on the internet) as 4.6 mJ per kg. <

That’s very wrong. I’ll be gracious, and assume that the author simply made a typo there. I believe that he meant megajoules per kilogram (MJ/kg) and not millijoules per kilogram (4.6 mJ/kg).

Big difference.

I love Scott Manley! Thank you for this. The man is brilliant.

Join the wreckage of the Titanic! Book your one-way trip!

Two things:

First thing: We don’t know for 100% the carbon fiber portion failed first. It could have been an end cap or a window. If I had to bet my life it would be on the carbon fiber failing, but it’s not absolutely certain at this moment.

Second thing: Where the sub wreckage was found was, according to what I’ve heard, right where the sub was headed. So why did it take several days for that area to be scanned? Why didn’t they START where the sub was supposed to be?

[Basket_of_Deplorables]

mJ is “milli-Joule,” or 1/000 of a Joule.

Want to check your units again?

Did you mean MJ, MegaJoule, 1,000,000 Joules?

Here is a photo taken by a submersible of the area showing the passengers....

[P.O.E.]

This one should be on the Math SAT.

I actually studied mechanical engineering, but only worked in that field for a half a year.

IIRC carbon fibre has a higher tensile strength than steel but has a catastrophic stress failure point - so great for say airframes with low pressure but back for deep sea. When it breaks, it does so suddenly with no warning.

But I’d like to read what mechanical engineers who actually stayed in the field and have experience have to say
