the towers.
each floor only supports a the floor above it and a bit more.
its a bit like on the american football field. one player after another jumps on the quarter back, each player supports the next. you drop all that weight at once on the quarter back and he's crushed.
the same happened with the towers. the plane hit. stripped some of the steel of their fire protection. the jet fuel burnt for a short while and the steel while not melting warped. as soon as the steel warped even a fraction. the weight of the floor above it grew exponentially to the weight of the whole building about it. like the buttress of a cathedral the weight of the roof travels down through the buttress and in doing so is fully supported. twist of move the buttress and the roof collapses.
the steel on each floor allows the weight of the floor above it to flow downward. the weight isn't trying to push the steal sideways, it's impossible for it to do so. but once the steel is warped which is what happens if it get red hot. (steel will glow red hot at 600 degrees or even less. ) put a knife over a a calor or propane gas flame and see for yourself. (gas burns at about 600 degrees. try it and see) it will turn cherry red. in this state the metal is liable to bend and fold under excessive weight. once it does bend, even fractionally the weight above has more force. the weight above now has movement as an added force (velocity) because of this added velocity the weight grows.
example. a fist weighs 1 kilo if you move it fast enough it can have over 400 kilo of weight, the bigger the mass the less velocity it needs to have a lot bigger force. just moving at an inch an hour the weight of the building would have a tremendous amount of extra energy.
i think it was traveling much faster than that. so on one or two floors the steel got hot (didn't melt) and warped. after that it couldn't support what was above it. as for windows popping out as if they were exploding before the collapse got to that floor; air pressure. the pressure in the floors below the falling floors would have had a tremendous pressure exerted upon them. it would make no difference if every door was locked and bolted. they would have been blown off like matchwood. the resulting pressure wave for so much weight would have been huge.
the collapse of the building started slow. then it pick up speed as each successive floor collapsed. that it they fell was inevitable.
build a pyramid of cards and take one out, the pyramid collapses.
stand an egg on it end and you can stand on it. move it off center a fraction and it breaks .
but a board with a 100 nails on someones back and you can stand on it without injuring him. do the same thing with two or four nails and he's dead lmao.
it all boils down to stresses. it has little to do with melting or not melting.
if you simply heat steel and them it cools rapidly it becomes brittle. you effectively turn the steel into cast iron.
and sideways movement and it will break at the height that building was with the floor of windows blown out, the cooling would be very quick. again a building of that height has sideways movement. couple that with warped steel and the momentum of the upper floors and it would be a miracle if it didn't collapse. and not i have no links.
i don't need one to prove steel glows red hot at less than 600 degrees.
i don't need one to show that metal at 600 degrees can bend or warp under a small amount of weight ( it's why they fireproof them) if as you say they can withstand any heat higher than can be generated, why do they fire proof them?
i don't need a link about mass and momentum
i don't need a link about pressure waves and there existence from a collapsing mass.
i don't need them because these things are all fact.
i think they fell because the plane hit them.
