Aluminium Baking Trays Can An Air Fire Really Significantly Weaken Steel So That It Can Fail?

This experiment was conducted in California Involuntary a gasoline truck and a steel bridge. The bridge collapsed.
Your test is not representative of what happens at the WTC, and is an indicator of the level of scientific understanding of EC WTC.

Ooooh ... I love the further details. Friend, if you have a PhD (the real) would have been granted by the Moonbats Crazy School. Common sense says that the test is completely useless.
Steel at room temperature: 100% resistance
Steel-50F: 111% resistance
500F Steel: 91% of the force
900F Steel: 76% of the force
1100F Steel: 69% of the force
1350F Steel: 44% of the force
Steel> 1700F \\ \\ \\ \\ \\ \\ \\ \\ u0026lt, 10% of the force.

Have you ever seen a blacksmith hammering steel at 850 degrees? Why does it work?
The temperature was limited to the World Trade Center from 1100 to 1500F.
All you need is a lack of will on the ground floor, and nothing will stop them. The point is that the building was built to withstand. Thirty-storey drop of 10 meters and see what happens with nothing inside or underneath.
Try this little experiment in the confines of an oven, not on the air and see what happens when the temperature is generated, as in the WTC.
No experience needed. I have personally converted planted tube steel, structural improvements in the processing plants, forest fires heat into the ground very similar to liquid fuel, the steel enough to fail to start.
This material was lightly loaded. If it is a measure of stress similar to that in a large building, which failed completely.
You should be aware that steel in a large building is currently relatively high level of stress or strain have. It is a way that the cost of construction is still down. Steel loses much of its strength at temperatures of about 1000 ° C. A temperature well below the temperature of a fire of fuel or kerosene.
I think you pointed to the theory of the WTC collapse, caused by burning kerosene. Steel has a melting point of 3000 degrees celsius +. Times as high. can be achieved with large amounts of kerosene in a closed room.
Even if it was a controlled demolition, it is clear that bin Laden and Al Qaeda? Is there justification for Islamic terrorism?

I ask myself, my own purposes. If the building fire can weaken structural steel at the point of failure, why the building code requires that the steel has an insulation layer. Certainly, it is necessary to keep the steel from too cold!
Developed Suppose that the World Trade Center by competent engineers was. It is assumed that the design of the tallest buildings in the world, have proposed received the special attention that some of the leading experts worldwide.
He took the task of designing a thermal layer on the steel members in order to protect them from the heat of a fire in the building. What if the steel is not the heat from the air "fire" involved?
If he knew anything, metal, you know that all the metals like steel to change their behavior when heated, and not only when they participate in their "melting point".
Combine the fact that the members thermal coating of steel largely by the mechanical action of the had been driven 747, the heat was far superior to what was done outside of a few grams of fuel and steel members were enormous pressure and subject to expulsion for the same purpose.
It is a testament to the designers of the buildingTorres was as long as they have done, given the horrific circumstances of this terrible day.
Please do not pollute the memory of those who died on 9 / *** Visit 11 with its wild rumor-mongering and conspiracy theories that violate the generally accepted knowledge engineering.
emperature be maintained - All right. So why not simulate a real experiment, the actual conditions of the soil (and a few stories from the top and bottom), and take some measures the actual temperature?
.
The WTC was not only a normal load and fire. She had an enormous influence that was certain to weaken the main structure is a normal charge + PLUS + The reduction in allowable by fire.
WTC consisted of an outer ring of columns built (244 columns of 100 cm away). Of course, you may use the photos from the fact that many of them have caused damage.
So you do not take into account the deformation of mild steel by fire. In a buckling failure of the collapse of small perturbations can lead to dramatic results.
If you are an "experiment" in your garden, as you knew that you had loaded the steel its limits? The permissible limits of the steel and MMPD HDBK-5 are A-and B-basis, the actual maximum rate may be higher at 10% -20%. Steel in a variety, how do you know that you are using the same steel in the WTC?
In reality, a very different experience, and I can tell you unequivocally that steel weakens substantially in air temperature fuel fire.
I have to use the hobby .... The manufacture of knives.
Yep. I take the normal carbon steel containers are available in any hardware store and the creation of decent Smith (OK, not so decent) knife. Believe me, the forge, not improvised generate anywhere near the melting point of steel. However, for some reason you can bend steel, and hammer it into shape.
And if you can. You do not have a forge, and have no interest in that one? It should.
Get a piece of steel, and on top of the stove. An old butter knife will work well. With tongs, recommend Vise Grips. not stick (please burn) the knife into the flame (or in the coils on the stove when an electrical system. Sorry, have those of you glass stops should play elsewhere.) Allow you to a moderate level from red to all steel.
Then fold. We & # 039; t so difficult, and is somewhere in the range of 50 pounds of pressure applied more or less. Now imagine, what was the pressure of the steel in the WTC building low.
