[extracted] New(?) 9-11 stuff

See above. I gave all the data.

Except supports, I did not include those which only give less chance of shear. The shear strength of steel is magnitudes greater than concrete.

You did not even know how to calculate the correct area you lame-wad.

You are worthless lying waste of air and you have done none of that.

Avoiding answering questions by saying "I answered them already" and thinking that anyone is going to be persuaded is up there with thinking the Earth is flat or bullets cause damage by resting on targets.

Next question - how have you not been sectioned? I dread to think that a cretin of your calibre is just roaming the streets unsupervised. Or are you under professional supervision right now? Is that why you have set hours when you post?

Oh, yeah, surface area vs cross sectional area calc mistake was a brain fart - you are right that it is pi*r^2h vs 2*pi*r*h. I was thinking about all the other stuff in that post, it wasn't important. That one is yours. I made one irrelevant mistake equivalent to a typo, you make multiple material mistakes per post, half of which I don't even bother to point out.

Shouldn't be a huge burden for you to replicate it point by point, then. Quote my post, and replicate your answers question by question. Easy peasy lemon squeezy.

I told you how to calculate the shear stress.

I told you how to calculate the correct area for a load under shear stress.

I gave you the thickness of the concrete.

I gave you the minimum shear strength of concrete (no reinforcement).

I gave you an estimate for the load based on the public data for "the meteor", the biggest piece of debris that could possibly cause damage to a neighbouring building.

I gave you the estimated area of impact using photographic evidence.

I gave you photographic evidence of the damage to WTC6.

I showed you a load the mass of the meteor cannot possibly fully rupture a concrete floor.

I estimated the KE of the meteor having fallen from the 55th floor (and inexplicably been fused together, steel and concrete under huge heat and pressure - further evidence of the Hutchison effect btw).

I showed you multiple AI models whether this KE can shear the required area, both direct and shear area for good measure. Negative. Meteor cannot have sheared one floor never mind 8.

After all that d2 asks

"What was the area again?"

This is done.

Whatevs.

Doesnt make a bit of difference anyway.

Listen, you dumb ****ing twat. I asked you some specific questions. "I told you before" is not an acceptable answer, because you are a lying **** and you didn't. So answer the questions or go **** yourself.

So, it appears that dumbdumb is doing his usual thing when asked the hard questions - "I answered this already". "I posted the map already". "I wiped my ass already". All straight lies.

Billy - you are an abject moron, and if you have not yet been locked up in the interests of safety for the general public, you should have been. You are a danger to yourself and others.

AI is pretty thorough on this, if we're using that now.

[quote="Google Gemini with prompt What caused the hole in the roof of WTC 6?"]
The hole in the roof of WTC 6 (the U.S. Customs House) was caused by massive falling debris from the North Tower (WTC 1) when it collapsed.

While the "crater" in the center of the building looked distinct and unusual to many observers at the time, forensic engineering reports (primarily by FEMA and NIST) confirmed the following:
1. The "Hammer" Effect

When the North Tower collapsed at 10:28 a.m., it didn't just fall straight down; it "peeled" and expelled massive sections of its steel exterior and core structure outward. WTC 6 was located directly at the base of the North Tower's northwest side. Huge sections of the North Tower fell directly onto the roof of the much smaller 8-story WTC 6.
2. Structural Failure

The debris from a 110-story skyscraper carries a literal mountain of kinetic energy. The weight of the falling steel and concrete was far beyond what the roof and internal floor trusses of WTC 6 were designed to support. This caused a progressive collapse of the building's central interior:

The debris punched through the roof.

The weight then "pancaked" the floors below it all the way down to the basement/concourse levels.

Because WTC 6 had a steel-frame design with large open areas for the Customs department, the center was structurally vulnerable to this type of vertical impact.

3. The "Hollow" Appearance

The reason it looked like a clean "hole" rather than a pile of rubble is that the debris fell into the building. The exterior walls of WTC 6 remained largely standing, creating a shell around a hollowed-out center filled with the remains of the North Tower and WTC 6's own internal floors.
Common Misconceptions

Internal Explosions: Some early theories suggested an internal explosion caused the hole, but investigators found no forensic evidence (such as residue or outward-facing blast damage) to support this. The damage was consistent with a "top-down" impact.

The "Craters": There were actually several areas of significant impact, but the largest one in the center became the most famous image of the building before it was eventually demolished during the cleanup.

Summary: WTC 6 was essentially "crushed from above" by the falling weight of the North Tower.

The AI just gathers information from what is available online. So we might as well just read the NIST report for the above info, which is the main info source. Notice the lack of quantitative info given.

The way I used it is to ask specific questions about the load the structure can take vs the applied load. We then get summaries from experimental data and an interpretation based on that data.

Now, you also need judgement. Some AI responses do not give the correct solution. For instance, if you take the microscopic energy fracture for unreinforced concrete it is found empirically to be 2 mJ/cm2 which gives 20 J/m2. Not very strong. Some AI responses are based on that but at the most this merely cracks the surface. At the macro scale for full shear we use the shear strength of at least 2 MPa. But that is only half the picture. Through the process of shearing there are energy losses to heat, sound and deformation. The correct AI responses factor all this in.

So you need to know what you are doing and read the original sources always. Which I did. That is why I know this.

Yeah no sht sherlock. Don't use it if you don't want others to do the same, hypocrite.

Ah, I see why you struggle. Good catch.

Funny, you never read the nist report or the bazant report properly.

I dont want to be associated with someone called nut nut.

The secret is not successful. That does not matter. All that matters is the political class.

If you work or have ever worked for an organisation then you know how it works. You don't question, not really. The guy who questions is the union rep who sooner or later meets his demise. The smart move is not to question, "ours is not to question" is the mantra of success in an organisation. Pretend like everything is good. Be nice to the boss, suck up a bit and keep your job. Maybe get a bit more. You have mortgage payments, car repayments, your kids shoes. We are like in the Eastern bloc, or today North Korea, Iran etc. We are the same, in essence.

I would not speak bad of my employer even outside work or anonomously. It is bad form. I assume people mostly share this view. Whistleblowing is different, and that takes real balls which most people have not got. And NASA isnt doing anything "bad", except tell a few porkies, but it brings us all together, we are all going to space together! Right?

There is a sinister element. This is the military-industrial complex, NASA is located within that, in what we might call the psychological warfare division. This goes back to the heart of WW2 when the psych warfare divisions were created such as the OSS which became the CIA, and jolly old boy Brigadier John Rawlins Rees who set up what would become the Tavistock Institute - these guys planned the fire bombing of Dresden etc, psychopathic war criminals.

So what does this have to do with NASA? Unfortunately they are not a friendly civilian agency. They are US military, do not be fooled. Why is the military interested in "space science"? First it is not science. Note they now have a "science desk" at the command centre, they never had one before! Now they do "super cool science" with pics of the Moon. It's a front for off-the-books classified ops. And a cold war/cold war 2.0 front. And not "for control of space" as the idiotic "leftists" will tell you, but for the psychological effect of being dominant, ahead of your adversary, in control. And a convenient cover for siphoning cash for a few death squads regime changing in some south american backwater or whatever god forsaken place. Oh but they are getting ass kicked in Iran ofc. Who knew. The artemis is as desperate an attempt to exert control as is the failed regime change in Iran. As the proper pundits will tell you, former army men, they would need 900k troops to secure Iran. Never gonna happen. So on one side of your TV you have the "great scientific endeavour" and on the other you have a friggin maniac threatening the world. I mean just look at the actors on this bloody artemis 2 tomfoolery. Is anybody fooled? Really?

Well we won't get fooled again. And that's another Billy Shears reference. For those who know.

Hey ****head, so, you can shite on for paragraphs on end about your dumb**** space laser "theories", but you can't take the same time to respond to some questions to clarify your most useless and most piece of **** model.

I see, I see.

No... I can imagine.

Hard to see what Rees, an Army psychiatrist, had to do with the bombing of Dresden, which was ordered by the Air Staff (and, for the USAAF, by Combined Strategic Air Forces Europe) because Churchill wanted a series of attacks on 'Berlin, and no doubt other large cities in Eastern Germany,' to support the new Soviet offensive in the East, and the Americans agreed. The cities listed and attacked by Eighth Air Force and/or the RAF were Berlin, Leipzig, Dresden and Chemnitz.

I admit I don't know what The Who have to do with Sgt Pepper, but I'm surprised you didn't know that, while NASA did of course hire Stanley Kubrick to fake the Moon landings, he couldn't get the effects he wanted in the studio (the usual problem of a sufficiently intense single light source throwing parallel shadows, I expect), so they had to go and shoot on location, and hang the expense.

What, for a well-known joke?

Big Hitler fan, are you, then?

Mine was a lesser known joke, apparently.

I must support an evil basterd either way then?

Although intelligence services make use of a lot of odd people with particular connections or abilities, Aleister Crowley was pretty much just a crank and a grifter. Hard to imagine either Captain Cumming of the Secret Service Bureau (later MI6) or Captain Kell of MO5 (later MI5) having any use for him before or during the Great War. As for his biographers' claim that he was recruited at Cambridge, that was ten years before either of the British agencies was created in 1909.

As psychology and psychiatry are arguably not based on a genuine body of knowledge (we just don't know that much about the brain), they're open to dubious persons, and the Tavistock has been known to host a strange culture -- see the gender-clinic scandal -- but I doubt its staff were ever a Hidden Hand controlling the Beatles or EMI.

Sorry, but anyone that doesn't realize the Artemis and Apollo missions were 100% real is a fing dmbass.

And that's just a fact.

Simple ai research of your lastest flimflam theory:

A 100 psf (pounds per square foot) floor is designed for high-load commercial or industrial use, but it cannot withstand the total collapse of 5 floors above it. The impact forces from falling, combined with the accumulated weight of multiple floors, far exceed designed safety factors, creating a progressive collapse scenario.

It was 20 years ago today, sgt pepper told the band to play... Crowley having died in 1947. In "the memoirs" the protagonist "Bill Shepherd" does not quite reveal his Crowley connection but there is something there. Perhaps not his father (although look at the young Crowley...) but perhaps an "uncle" who may have initiated William into service. What service? His Majesty's satanic service of course! For instance promoting drug taking was a priority among many bands post 1966.
