Submersible Titanic Tourist craft goes missing

We're not talking about flexing stress with submersibles we're talking about compression ans 15,000 PSI crushing pressures. Epoxy resin and carbon fibers are NOT suited for that type of pressure dynamics, metals are...

 

An aircraft made of carbon fiber reinforced polymer would also undergo expansion and contraction with temperature changes, but too much less degree than metals, because of having a much lower coefficient of thermal expansion.

The problem with expanding and contracting materials is not the expansion and contraction per se. If the structure is one material, then all of it expands and contracts together. The difficulty in design becomes when dissimilar metals are connected or bonded to each other. They expand or contract different amounts which sets up stresses between them.

 

No shit. I was answering a question regarding flight. See Post #328

 

Online mockery of Titanic submersible leaves cultural observers sickened: 'Garbage dump of vile commentary'

it’s not just us being crude about this apparently. And not just you who is offended by it.

 

You hear of airlines being sued after crashes, but I have never heard of the pilot’s estate being sued.

 

Interesting quote from that article:

 

This isn't unlike the jokes after the Challenger disaster (e.g., NASA means "need another seven astronauts"). It may be magnified because of the broadcast and instantaneous nature of social media, but people typically use humor in grim situations to cope.

 

There is definitely a competition on these pages to see who can be the most irreverent and disrespectful with their comments and memes. It's a culture on social media. Criticize it? Watch the response to those that do. It is ugly.

 

I think part of it is simply distance from a situation. I remember the nasa jokes well. When we watched coverage of the explosion the mood was always somber and respectful but I heard the jokes as a kid and laughed at the time as well. The culture online today is just different. Way more for shock value and likes. The coping aspect in my opinion comes into play for people closer to the situation in various capacities.

 

Perhaps. I've always used humor to cope in situations like this personally. I know that some people can handle that and others get offended. I always went out of my way to make sure I knew my audience. That's part of why I blame the nature of social media, the audience is global and ever-changing and it's much harder to keep from offending anyone.

 

Well put.

 

Lack of bodies is how we know the Titanic isn't real.

Interesting article back when the submersible was built. By the way, the Cyclops 2 name was changed to Titan. The components were a composite hull, titanium end caps, and an acrylic viewport. The article discusses exactly how the structure was made. They even give the brand names of the materials used in making the composite.

They talk about all the structural health monitoring that was being built into the design of the submersible. It sounds impressive in the article. I wonder what went wrong along the way from good design to catastrophic failure?

I have got to stop reading TH during lunch.

 

The CEO of the airline isnt usually flying and building the plane though either

 

I think experts are saying the the design was crap. End caps connected by a carbon fiber tube. If it was all carbon fiber in a sphere shape maybe (but probably not).

Within reason though. His family isnt the guilty one, ya know?

 

Gallows humor is a defense mechanism against contemplating the inevitability of one's own death. I would even say it is insensitive to demand that others hold it in if that is how they need to process it. That isn't to say it should be shared with the world.
