I’m not sure what that means, but if it were possible to remove the central core, would the “outer skin” remain standing? What if you could remove the outer structure, would that have weakened the core? ---

You realize your implicating this organization with over 120 000 members as part of the conspiracy now ? I’m not implicating anybody. Read my posts. I had a doubt about one thing, and it made me start digging. I got attacked here, so I defended myself. I don’t know what happened, nor do I calim to. There is, IMHO, compelling evidence that the offical story is BS. With every thing that has happened since 9/11, I think I must investigate more, since I have a doubt. By the way, it only takes a small number of people to conspire. The rest are just robots, just doing their job, never questioning. ---

Though I’d greatly prefer to follow the slow points-of-agreement discussion described above, I admit I don’t get the significance of the fall speed. How much slower than free-fall _should_ it have been, and assuming the speed was faster than it should have been, what does that prove or disprove? ---

> [@ivan\_astikov](#): > > I’m not sure what that means, but if it were possible to remove the central core, would the “outer skin” remain standing? What if you could remove the outer structure, would that have weakened the core? The answer is actually pretty complex. Neither the central core or the outer columns would stand on their own. The inner core is too slender to stand as a freestanding structure without bracing. If you could somehow instantly remove the rest of the structure, the central core would stand briefly, then bend or buckle and collapse. The outer skin by itself would also collapse for much the same reason. The columns would be able to stand in compression, but without lateral bracing would bend outwards and fail. The floor pans inside the tower provided this lateral bracing by connecting the core columns to the skin columns. Only when the entire structure was intact could everything stand. You can see the result of this if you carefully watch the collapse sequence. The collapse started where the structure had been weakened by the airplane impacts and resulting fires. Much of the falling debris would have hit the floor pans of each floor. Each floor pan was really only intended to hold the weight of that floor’s contents, so would have failed instantly. As the floor pans failed the outer columns lost lateral bracing and peeled outwards (though they acted as a bit of a funnel to channel the falling debris inside the tower as they did). The central core may have remained standing for a few seconds before buckling and collapsing. It is exactly the collapse sequence you would expect from that structural design. ---

What if you could remove the outer structure, would that have weakened the core? No, other way around. Remove the outer skin, aka facade, and the core will remain standing. Remove the inner core, and the outer skin would crumble to the ground. Of course, I’m not claiming that the core of the WTC would have should have stood 110 stories after the buildings were attacked. Look, AndrewL, I’m not going to post a link. Look up Modern Marvels on the History Channel. The Sears Tower was built the same way. ---

You make a claim, you back it up. Although I will point out that 5 minutes of research shows multiple sources showing that the Sears Tower is a bundled tube style structure in which much of the load is carried by the outer shell of the building, rather than being carried by a central core as you claim. ---

[Debunking](http://www.debunking911.com/freefall.htm) the free fall fallacy: > [@](#): > > n every photo and every video, you can see columns far outpacing the collapse of the building. Not only are the columns falling faster than the building but they are also falling faster than the debris cloud which is ALSO falling faster than the building. This proves the buildings fell well below free fall speed. That is, unless the beams had a rocket pointed to the ground. > > Just look at any video you like and watch the perimeter columns. > > Deceptive videos stop the timer of the fall at 10:09 when only the perimeter column hits the ground and not the building itself.

It is rather the conservation of momentum that slowed the collapse together with a small additional time for the destruction of each floor. > > ``` > Below are calculations from a physics blogger... > > When I did the calculations, what I got for a thousand feet was about nine seconds- let's see, > d = 1/2at^2 > so > t = (2d/a)^1/2 > a is 9.8m/s^2 (acceleration of gravity at Earth's surface, according to Wikipedia), [He gives this reference so you can double check him.] > d is 417m (height of the World Trade Center towers, same source) > so > t = (834m/9.8m/s^2)^1/2 = 9.23s > OK, so how fast was it going? Easy enough, > v = at > v = (9.8m/s^2 x 9.23s) = 90.4m/s > So in the following second, it would have fallen about another hundred meters. That's almost a quarter of the height it already fell. And we haven't even made it to eleven seconds yet; it could have fallen more than twice its height in that additional four seconds. If the top fell freely, in 13.23 seconds it would have fallen about two and one-half times as far as it actually did fall in that time. So the collapse was at much less than free-fall rates. > Let's see: > KE = 1/2mv^2 > The mass of the towers was about 450 million kg, according to this. Four sources, he has. I think that's pretty definitive. So now we can take the KE of the top floor, and divide by two- that will be the average of the top and bottom floors. Then we'll compare that to the KE of a floor in the middle, and if they're comparable, then we're good to go- take the KE of the top floor and divide by two and multiply by 110 stories. We'll also assume that the mass is evenly divided among the floors, and that they were loaded to perhaps half of their load rating of 100lbs/sqft. That would be > 208ft x 208ft = 43,264sqft > 50lbs/sqft * 43264sqft = 2,163,200lbs = 981,211kg > additional weight per floor.

They're almost equal! That means we can just multiply that 10 billion Joules of energy by 110 floors and get the total, to a very good approximation.

Let's see, now, a ton of TNT is 4,184,000,000J.

That's over a quarter kiloton. We're talking about as much energy as a small nuclear weapon- and we've only calculated the kinetic energy of the falling building. We haven't added in the burning fuel, or the burning paper and cloth and wood and plastic, or the kinetic energy of impact of the plane (which, by the way, would have substantially turned to heat, and been put into the tower by the plane debris, that's another small nuclear weapon-equivalent) and we've got enough heat to melt the entire whole thing. > > ``` I think this particular aspect has only been address 5 or 6 times in the past, so it probably bears repeating.

How much slower than free-fall _should_ it have been, and assuming the speed was faster than it should have been, what does that prove or disprove? Yes, I agree that it is fair to say that several hours into a large fire, a building’s steel support members could be significantly weakened. I’ll even go further and say that the building could collaspe. We are talking about tenths of second in the case of the WTC. But they are very important tenths. Structural engineers have things mapped out. A good number of them are saying that the speed of the WTC collaspe approached that of controlled demolitions, in which case they cut lower structural supports. They take exception due to the fact that the WTC supposedly had no damage to its lower supports. So the speed of the fall should have been decreased due to the resistance of the intact supports. ---

> [@ironbender](#): > > Structural engineers have things mapped out. A good number of them are saying that the speed of the WTC collaspe approached that of controlled demolitions, in which case they cut lower structural supports. Thus, we can conclude that they are talking out of their asses. The speed of the collapse is an **unknown**. The building disappears into its own debris cloud long before the building had finished falling. Remember, the CT’ers think the building fell at “free-fall” speed, which they quote as 9 seconds. Here’s a little video of the collapse: [Linky](http://www.youtube.com/watch?v=qLShZOvxVe4) At 9 seconds, the camera is pointed at the sidewalk as the person filming started running. But the camera pans back around to catch the Trade Center tower still intact to around 30 stories (we have the 22-story Marriott Hotel in frame for comparison.) By this point, we’re 11 and a half seconds into this “free fall” collapse. This camera cuts out before the building is all the way down (as evidenced by the sound) and thus, the video switches to a sound source from the other tower, which ends at 15.28 seconds. And, surprise surprise, that amount of time fits squarely with the NIST report. No fuzzy math needed. ETA: Still, the point remains that nobody really knows an exact number–what we do know is that the 9-second-freefall speed number is bullshit. ---

The first parargraph of your quote is telling. Explosives are highly suspected in the case of the WTC, no one has every deined that. The millatary has expolvise thermite. The rest can be considered jeberish to cover it up. ---

[QUOTE=ironbender] The millatary has expolvise thermite. [/QUOTE] There is no such thing as ‘expolvise (sic) thermite’. Thermite isn’t an explosive, it uses a chemical reaction to burn through a material. Even the mythic ‘nanothermite’ is just thermite with the oxidizer more tightly incorporated into nano sized particles in order to make the chemical reaction less chaotic and more predictable. -XT ---
