Get a steel rod or pole. Heat it at the top. It becomes pliable. Then leans out. The inner floors collapse. Basically a mushroomjng effect.Headman, how did a fire at the top of the building heat the metal in the bottom 40-50 floors?
I don't think it was some government conspiracy, but I found the points in this video interesting and believe structural engineers probably understand this better than I do.
people who continue to send this crap out have no grasp of general engineering principles or physics for that matter
The fuel went all the way to the lobby. It burned from almost to the top to the bottom.I don't either, so how about an explanation in layman's terms explaining how the towers fell at a freefall rate?
I just explained it.I don't either, so how about an explanation in layman's terms explaining how the towers fell at a freefall rate?
I just explained it.
The metal beams heated and expanded. They became like hot wet noodles. The outer vertical beams spread out and the inner floors had nowhere to go but down.
No. It was like a deck of cards at that pointWouldnt the bottom floors have to crumble previous to the upper floors falling to allow for freefall rate?
No. It was like a deck of cards at that point

Google it. Structure is weakened by fire. Floor above collapses on floor below since the floor below was weakens it couldn't support the mass above. Now instead of one fooor falling you have two on to the floor below. That floor is also weaker due to fire and can't support weight of two floors collapsing above. It's a domino effect explained by simple physics. The mass keeps getting bigger and bigger meaning force keeps getting bigger and bigger, thus the entire building collapsing.
Why are floors far below the fires weakened?
I didn't say the floors far below the fire were weakend. If you take a second and think critically of what was typed you'd understand. The floors directly where the plane crashed and fire started were weakened. The fire did spread I don't know how far down the building, but once it starts coming down the mass falling continues to increase as does the acceleration. This means the force coming down continues to increase more than likely exponentially with the increasing mass.Why are floors far below the fires weakened?
Did you not read what was posted above?

In terms easier for you to understand. Once it started coming down nothing would stop it PERIOD END OF DISCUSSION
There's nothing stopping it once it gets moving. drop a brick through a window. It doesnt slow down. Once the main support structure is compromised it no longer functions properly.I'm not questioning that it would come down. I am questioning that it would come down at freefall rate.

Yeah I did. But I don't accept a fire that lasted less than an hour weakened steel beams 10 - 20 floors below it.
aviation fuel.
Put this in a perspective you might understand: someone dumps a whole quart of varnish on a counter top just beneath the poor quality cabinet you just hung. The varnish will burn through the bottom of the cabinet until all the heavy contents dump straight down. Additionally, the fire will burn through the counter top, so now you have your recycled cool whip and butter containers in a melted goo pile all the way down to the floor.
that help?

Put this into perspective. When all that stuff burns and falls through the counter top, that base cabinet under the counter top has a shelf in it attached to the sides. It meets resistance.
No. I said that based on the force the resistance of the floor below wasn't enough to stop the load from above. The fire was t localized to one floor or area. The plane exploded on impact sending jet fuel all over the place starting fires all over the building, not just at the impact site.Are you saying there was zero resistance to those floors falling through another floor?

Good Lord. The outers supporting beams were weakened and then when the floors above starting going down it was like folding up an accordion.Why are floors far below the fires weakened?

I swear you are being intentionally dense in this conversation just because. It really isn't that difficult
I've answered that. The force was so large that the floor underneath the collapse wasn't strong enough to slow it down enough to make a difference.No, you and the others are being dense. Once again, I am questioning the possibility of the building collapsing at freefall rate. It is my understanding that physical laws state that's impossible. Do you or anyone else in this thread understand that? If physical laws allow it, let me know. Otherwise resistance would have slowed it down according to my understanding, even the brick through glass would have been slowed.

And yes the glass would slow the brick but you wouldn't be able to tell just by watching it with the naked eye
