What are the only 3 steel framed buildings to EVER fall due to fire???????

Question

And how does anyone with common sense believe the media and not architects, engineers, pilots, demolition experts, and scientists???? No, the people at popular mechanics know all! LOL, LMAO,ROFL. Freefall in the path of most resistance!! DE DE DEEEEE LOL, LMAO

Hey cirric, what about building 7. And the molten steel. Interesting fact steel melts at 2750 degrees F, an open air jet fuel fire under perfect circumstances can only burn at a maximum 1800 degrees F. FYI the empire state building was hit by a very large airplane, with Jet fuel in it. It burned on 6 floors for 8 hours and didn't fall. They fell in the path of most resistance at freefall speed! And the melted steel is proof of DEMOLITION!!! Ask any DEMO expert not from popular mechanics!!!

RIGHT ON KAZEL! The truth will set them free of their govt. sponsored chains!! FREEDOM is NOT WAR FOR OIL!!

Your right fire weakens steel, BUT IT CAN NOT MELT IT UNDER THESE CIRCUMSTANCES. WTC7 had molten stell found under it and it was never hit by a plane!!

Another question for you guys, how does an aluminum airplane fly at 500 MPH+ at 700 feet altitude without being ripped to shreds. CALL boeing and ask them what the top speed is at this altitude, they will tell you no more than 250mph. Planes flying that low can not fly as fast as the 2nd plane was when it hit!! You all watch movies on TV too RIGHT??? You telling me that cause you watched mars attacks on TV it had to really happen. You sheep deserve what ever the govt. feeds you. ITS ALL LIES!! Check out this video. Architects and engineers for 9/11 truth!!!

I am going to repeat this for Mr Thermodynamics! WTC7 had molten stell found under it and it was never hit by a plane!! OK! GET IT! How does a building fall in the path of MOST resistance at free fall speed. The buildings fell into their own footprints! A quote from a DEMO expert "The art of controlled demolition, to bust a building into a million pieces and put it in its basement." I'd say that describes what happened exactly! Also most of the jet fuel was lost in the intial explosion. I would like you to explain how the whole building fell into itself, without toppeling over. People do the research and watch the movie I posted. The official story is complete BS. Another thing is the 9/11 government report NEVER even mentioned building 7. Larry siverstein collected 7 billion dollars in insurance money. Two weeks prior to the "crash" he revised the policy to cover terrorist attacks specifically. They also dont mention the asbestos Silverstein would have had to remove. LIES all LIES!

Lets see who benefitted, Osama- he is living on the run and can not do anything in any country without being executed! So on a scale of 0-10 he benefitted 0. Silverstein- he would have had to spend 1 billion dollars to clean all the asbestos out of the WTC, instead after the buildings collapsed he collected 7 billion in insurance money. On a scale of 0-10 he benefitted 10. Bush+Cheney(halliburton arms and oil dealers) needed a reason to invade afghanistan and Iraq in order to make billions off of weopons and oil. They also score a 10. Saddam hussein- He had to live in exile in an underground bunker, only to eventually be hanged. He scores a 0. No benifit. They wanted the war before this happened, as described in PNAC. It also states that the US needed a "new pearl harbor" to initiate their war. I'd say they benefitted 10 on the scale. Al-quieda- They have no resources and their #s have been reduced to nothing and are constantly hunted. They were created by the CIA. they score a 0 too!

Everyone needs to watch this 10 minute DEEK newz show about 9/11. He puts it in terms an IDIOT can understand!

Answer 1

Empire State building was hit, last time I checked it was up.
What about the third world trade center building? Why did it fall? Was there a small jet plane that hit it a few hours later or what?

Answer 2

It's really quite simple.

There is a fundamental thermodynamic law, that states:
deltaT = theta * Energy / deltatime

-deltaT is the temperature rise.
- theta is the thermal resistance of the media
- Energy is the total energy contained in the jet fuel
- delta time is the time between the airplane crashed into the building until it collapsed (about 1 hour for the south tower : 3600 seconds)

The energy contained in the fuel tanks can be easily calculated:

Well documented is: 23,980 U.S. gal for a Boeing 767ER. Let's round it down to 20,000 gallons.

Jet-A fuel has an specific energy 42.8 MJ/Kg, minimum (ref:
http://aviation.pertamina.com/files/aviation_turbine_fuel.asp)

Jet-A has a mass of 775.0 to 840.0 kg/m^3 (ibid), which leads to a mass of 58700 kg, which leads to an energy of 2.5 TeraJoules.

Plug that back into fundamental thermodynamic formula #1, and we have a couple of things to consider.

A. If deltaT is only 1000C, then theta must be 1.45*10^-7 degreesC/Watt, a patently ridiculous number (waaaay too low).

Or

B. use a more reasonable value for theta (like 4 for ten meters of air) and see that is is theoretically possible for the temperatures to rise to *way* over 100,000 degrees C in some 'hot' spots in the middle.

Granted there were other mechanisms (i.e. smoke mass) to carry heat loads away, but unless you can prove to me that those were the majority heat transport mechanisms *and* the thermal conductivity values were on the order of 10^7, I'll stick with the good ol' laws of thermodynamics.

One other point. 1 kiloton of TNT is equivalent to 4.186 TeraJoules of energy. That means that the energy in those fuel tanks was the equivalent to 1/2 a kiloton of TNT. It doesn't matter if it took 1/10,000th of a second to release (as in a nuclear bomb) or 1 hour, the energy is still *all* there -- mostly in the building, mostly in heating up steel to way above it's melting point.

Simple thermodynamics in action.

Answer 3

Steel does not do well in extreme heat. In fact, timber does better than steel in a high heat fire because the heat will char the outside of the wood which then acts like an insulator for a time. Most civil engineers know this.

Answer 4

The planes have been full of 20,000 gallons of jet gas. The homes does no longer have collapsed if there wasn't this plenty gas. This made the hearth so warm and an prolonged lasting hearth till the development's shape could no longer take it and it fell down.

Answer 5

It has been said the reason for the collapse was due to the fire retardent that was used to coat the beams were not completely covered and thus the heat affected the uncovered parts and caused the collapses. Right!!!!!!!!!!!

Answer 6

Hi. Every one that was hit by a large jet full of fuel at high speed. Or the debris and heat from them.
