when the towers collapased on 9-11, why did the top floors above the crash continue to collapse after falling?

Question

to the ground, it would seem that those floors would remain intact. Can anyone explain how this happened, there seems to be no logical explanation as to why the top floors would crush each other since there was no weight crasing into them.

Answer 1

Because the ground structure beneath them was destroyed. There was nothing solid beneath them. Also, they may have looked intact but surely, after the fall they were like a crackled eggshell, just holding together untill one brick of the structure beneath shifted, making it crumble down onto itself.

Answer 2

"Newton's 0.33 regulation of action states that for each action there is an equivalent and opposite reaction. So, at the same time as the suitable 12 flooring above the plane impact zone on the North tower of the WTC fell by the impact zone onto the decrease ninety 3 flooring, why did not the fall down supply up on the 81st floor? " I have a good more advantageous acceptable question. Why do you imagine Newton's 0.33 regulation of action implies it ought to? You look to have some idea that the rigidity of 12 falling memories must be attenuated to 0 by making use of crushing 12 memories below yet frankly, that shows one of those wondered ideas set that it is not available to carry close the position to commence.

Answer 3

"why the top floors would crush each other since there was no weight crasing into them."

Uhh, just all of their inertia. Hint: Buildings aren't meant to be moving objects.

Answer 4

The upper floors were weakend by the fire below and and the damage to the structure below also weakend the upper floors so the weight of its own structure and furniture. And impact with the ground finally did in the remaining structure.

Answer 5

Heat from the fuel burning within the plane's full fuel tank heated up so hot that it melted the metal beems above the "crash floor" that fortify the stucture for the floors above, then gravity kicked in.

Answer 6

The Twin Towers were full of explozives and the airplains had napalm bombs wich fired up the explozives... it was just a mather of time then till the Towers will start to collapse

Answer 7

The only logical explanation is controlled demolition.
See below for details.

Answer 8

Jet fuel burns really well. Heat rises. Floors above the crash were subject to extreme heat and they failed. Was that your question.

Answer 9

Good point, it looked like a demolition company destroyed it from the inside out like they do when wrecking a building, it was weird.

Answer 10

Maybe there was no support for them - no reinforcement.
