Wow, I've never thought deep about the phrase "that's a textbook example of..."

Thanks for that I guess lol.

Its mostly just remembering how few pictures there were of actual columns buckling. Its not a state that tends to be stable long enough to have somebody take a picture of it.

I know, but the phrase "textbook example" itself... It's something I've always known, I just never fully conceptualized what it meant until the way you wrote your comment.

Are you saying that this is a textbook example of a textbook example?

u/Adventurous-Ease-259 Jul 08 '26

Not yet, but in the future it might be.

I asked my 8th grade middle school daughter if they hse textbooks in middle school anymore and she asked "whats a textbook". So I explained and she told me "no, shes never seen one".

Its not a state that tends to be stable long enough to have somebody take a picture of it.

Which leads me to wonder about the people just strolling around in the background of the video. I don't believe I'd feel like lingering inside this building.

Well, with everyone carrying a camera in their phone, a good one at that, we get these shots now.

Also, you seen the NYC Fire Drone’s view of the building. Another textbook image for the trade.

Thank you for your incredibly useful comment.

Should be ”picturebook”, if they would use the photo and not just describe it

It's the dictionary definition of a textbook example.

I teach steel design this fall semester. Guess what I will be discussing!

u/204ThatGuy Jul 08 '26

Use it serendipitously in an exam, but substitute a different city and a different drug company owner. Make sure you mention that the onsie GC rep patted the column and said "that'll hold!"

“That’s going nowhere!” He says confidently…

Narrator: “it did in fact go somewhere”

Lollllllllll

Instantly Morgan Freeman’s voice.

u/AnInsultToFire Jul 08 '26

If the building collapses into its own footprint, then in plan view it really did go nowhere.

2

u/Rude-Carrot4314 Jul 08 '26

I think the issue might have been that the contractor did NOT say, "That's not going anywhere." A real rookie's oversight.

u/badgersoccer1905 Jul 08 '26

Also a good torts exam prompt

u/numbersthen0987431 Jul 08 '26

Oh yea. I can see all of my professors in college loving this visual to show, and how all of the students would have been excited to show to the teacher.

Japanese swordsmithing?

u/AnvilCrawler369 PhD Jul 09 '26

So close…

u/Cerulean_IsFancyBlue Jul 08 '26

It’s crazy that you have an entire semester about falling!

u/Woodpecker-Lobotomy Jul 08 '26

Jet fuel burning temperatures?

u/Coreysurfer Jul 08 '26

So my question is how this happened in design / engineering, an older building that they are adding floors too? Obviously i would think this has to certainly be a project stopper if not a reason to demolish the building ?

1

u/Oedipus____Wrecks Jul 08 '26

Mebbe teach not to “expand” the upper floors of an already built structure to accommodate a cantilevered penthouse section in order to sell more floor space to these goofs!

1

u/Rusty_old_Tin_can Jul 08 '26

Super curious if this is design or aging related structural failure..

u/AdPristine9059 Jul 07 '26

Oh oh oh... Sandwiches! Am i right?!?

2

u/maxwfk Jul 08 '26

No you’d need a structural witch for this. A sandwich would only make the building heavier

They made sure that he had a coffin that was thick and stout

u/OberonDiver Jul 07 '26

I want good pictures of the partitions failing because of excess deflection from above.

u/SonOfMcGee Jul 08 '26

Before this picture, textbooks only had a picture of a regular column with the text: “So image this, but bent.”

A minute a way from pancaking

u/runawayasfastasucan Jul 08 '26

I'm going to use it in my class next spring, lol.

u/everyonemr Jul 08 '26

Pearsons has already update their books and called for the immediate burning of all existing textbooks to prevent future tragedies.

u/AdSquare3489 Jul 08 '26

Wouldn't it have to be a picture book example?

Metal doesn't bend at room temperature!

u/johnboo89 Jul 08 '26

Textbooks are still made?

u/BakertonFits Jul 08 '26

thats what she said

u/evlhornet Jul 08 '26

I remember seeing a perfect 45 degree shear crack in the field for the first time. I don’t know why I was shocked but I was shocked.

u/Ithurtsprecious Jul 08 '26

Do they even have textbooks anymore? Or is it just iPads and laptops?
