The entire freaking floor was completely engulfed, and others too, above and below them.
To scale, each window was a few feet taller than an average person.
Ritazzo, This is just senior school level physics. The motion of bodies is governed by Newton's Laws of Motion and the third law states:Windows on the World, kudos for actually having an open mind and not just buying what others tell you to believe.
Its funny how as soon as you question the events of that day, in a realistic and unbiased way, you must be some sort of deranged nut. Just as quick as that.
An architecture forum is a good place to bring this up:
The North Tower was hit on the 92-98 floors (being generous, other reports 94-98).
The tower was 110 stories tall.
Therefore, 18 stories of building collapsed the entire rest of the building (92 floors). All the way down to the bottom.
The problem is, those 92 floors were undamaged, meaning they were fully ready for the weight of 18 stories.
So on 9/11, the weight of 18 stories totally destroyed the lower 92 floors in about 15-20 seconds.
And they say the 'crazy conspiracy theorists' are the ones who make things up
Rizzato,I appreciate your responses. Too often this conversation turns into someone getting angry for some reason, I never understood that.
While I am not an engineer, I feel as if we aren't giving the WTC structure enough credit. This is not a fragile structure, ready to collapse the moment an extra force is added to it.
This was a beast of a building, with 59 steel beams on each side, and large steel beams in the core. It is a disservice to the architect to assume the whole building would collapse because of some damage to the top of the structure.
I just have to add, about the car analogy. That car would pick up speed, yes. However, in the case of the WTC, as soon as the falling floors hit the undamaged floors, it would encounter resistance. Now, this resistance might not stop it at once..but we seem to be assuming this resistance adds up to..nothing? Take a moment to think about the resistance these floors would have encountered. This 18 story section is encountering a massive, undamaged beast.
Also, lets see if we can demolish a building in such a way. Go down 16% from top of building. Cut all exterior steel and core columns at this spot. We should see the top 16% fall one story downward, and then continue to demolish the rest of the structure. Lets ask some demolition experts about this.
The floors were the weak points in the building. If you go back to earlier designs of skyscraper such as the ESB, the floors would have been heavy steel supported at regular intervals by a grid of columns over the whole plan area of the building.To be fair, Rizzato has a point. By undamaged beast i'm guessing you mean the acre in size floor and all of it's trusses which would in fact be a load bearing beast because they all worked together to cary the load. However, the moment the building started collapsing (before it's total collapse) the floors were collapsing unevenly, and some trusses were exposed to heavier loads than other trusses. Even the tower's total collapse occurred unevenly.
It would make sense that the tower could collapse in such a way. What i still don't understand to this day is the total disappearance of the core.
