Aircraft : The Science Behind The Collapse Of WTC Can Jet Fuel Burn Hot Enough To Weaken The Steel Supports
my own understanding is that an explosion is the super heating of a liquid, aerosol, gas or particulate (such as flour) and that the heat generated can be many times hotter than the ignition point of the substance. But how, under what circumstance? I knoe firefighters know this stuff and structural engineers, possibly. Any of you on line? Can you please explain it? ~~~ Lillian T ~~~
Best Answer To Aircraft Question
Absolutely. But you must also understand there there are more forces in effect than that of just heat. It also has gravity, heat, torque, stress, mass above and below the structure, and fracture among many many other forces. The fact that steel can be heated and heated to a force to even slightly weaken it with these other forces acting upon it will in fact all contribute to the collapse. Simple physics really.

Answer 1weaken yes and did, but collasping all into a heap was proven impossible....many times ...where have you been?

Answer 3I don't see why the force of hitting the building with a jet plane is not enough to knock it down. Explosions caused by fuel would just cause additional damage. Have we really ever had anything to compare it to?
Answer 4Explosion do not melt steel, the extreme pressure wave pushes it aside, melting steel requires time for it to heat up. Why none of the people that believe the WTC towers were demolished interviewed the President of CDI is because he is the expert in the field. When Seattle demolished the Kingdome, CDI was the company hired to do the job.
Answer 5Its not the heat to melt or destroy the steel you just have to have enough heat to soften the steel and the weight of the building above will do the rest. This has been known since Victorian times when they used the new fangled iron beams in buildings and found that the buildings collapsed during a fire but buildings with the old fashioned wooden beams stayed up with the beams schorched by the fire but not destroyed. What it was, was the heating effect of the fire weakening the beam
Answer 6Without a doubt, a pool fire of jet fuel is sufficient to critically weaken structural steel.
Answer 7Not again. Please not again.

Answer 9Jet fuel burns plenty hot. Maybe not enough by itself to melt the steel supports, but don't forget there are other fuels inside a building, and those supports were already damage from the impact, so they just need to weaken a little bit, not completely.
Answer 10you do NOT have to melt steel to cause a failure. You only have to heat it enough to change the crystal structure of the metal. Jet Fuel does burn hot enough to weaken steel. and once 1 floor came down it was a domino effect.
Answer 11Very simple... and for the last time... A big airplane with lots of fuel made a big hole... that big hole took out a wall that was intended to support the building... the rest of the steel was enough to keep it standing... the fuel, burning very hot, WEAKENED (but did not melt) more of the steel... the combined effects of the missing supports and weak steel holding more than it was inteded to already caused the collapse... Now, for those of you that dont know, jet fuel is plain old kerosene with a few additives... kerosene is used in lamps for a reason... lots of heat equals lots of light...
Answer 12If you understand the principal of the operation of an oxy-acetylene torch, perhaps you can grasp what happened. Acetylene burning by itself will barely start a fire, let alone melt steel. Add oxygen under pressure and voila, it will not only melt, but, burn steel. If you heat a vertical beam to just past red hot, it will begin to crumple under it's own weight. Big fires make their own wind. That is why the western forest fires get out of control so soon. The fire burns air creating a vacuum and air rushes in to to replace the air that was burnt. Jet fuel in a confined space does the same. The inrushing air replacing the air that was burned acted like a cutting torch, heating the steel beams to such a point that they could no longer support the weight above.
