ubercookieboy (12/16/2015) [-] ![I was trained as an engineer, and I can confirm this. I can even provide an explanation.
When creating steel, it goes through four phases - Iron is mixed with a very specific amount of carbon, It is then heated to a specific temperature, it is then "molded" by a range of specific processes [Drawing, casting, etc], then it is cooled down at a specific rate.
Notice that I say specific a lot. This is because steel metallurgy is a highly refined, complex process that takes years to master. You can have all kinds of steel that are designed for different purposes.
When you mix iron with carbon it forms a grain structure on a microscopic level. The grain structure can be manipulated to give whatever combination of hardness/toughness is desired.
The final process of steel manufacturing is a cross between tempering the steel [Rapidly cooling] and Annealing [Letting it cool off over time]. This makes the steel rigid-hard, or Flexible-soft.
When a sufficient amount of heat is applied to a piece of steel it becomes denatured, meaning its properties change. As explained at the end of OP's video. Even if it has been allowed to cool down the steel would not be as rigid as it was earlier.
Concrete cannot withstand high temperatures. If the temperate is high enough it can damage the concrete's molecular composition, making it useless.This is why buildings are condemned and demolished if there was a large fire.
Now imagine you had a little brother, and he was standing on your shoulders to make a human tower. You have your arms firmly grasped on his ankles and he is stable. But he loses balance and topples over, taking you with him
This is why the towers fell over. Its internal infrastructure failed and the damage it sustained at the top took the rest of the building with it.
MFW conspiracy theorists don't have a clue about physics or chemistry, but try to tell me how materials work.](http://new.fjcdn.com/site/funnyjunk/images/transparent_pixel.gif)

rudeobuteo (12/17/2015) [-] Is that why BBC reported that building 7 collapsed before it actually happened?

anon (12/17/2015) [-] Alright, you're an engineer.
So you would know that when a material is in a molten status it is liquid.
Is that bar that he bent a liquid? Soft, yes. Weak, yes. Easy to bend, yes. A liquid? No. Molten? No.
To top it off he even claimed to have heated that piece of steel to 1800 degrees, 300 degrees more than jet fuel under ideal circumstances, and still it is not molten.
So, does this disprove the argument that jet fuel cannot melt steel beams? Quite the opposite i'd dare say.

ubercookieboy (12/17/2015) [-] I think the motivation behind "Jet fuel can't melt steel beams" is implying that just because the beams were not molten, they should not have failed to hold the building up.
As OP has demonstrated, a heated piece of steel simply doesn't have the rigidity to be fit for purpose. Even if it was allowed to cool it would be much softer than it was before, making it unsuitable for supporting the buildings weight.

anon (12/17/2015) [-] I've heard people argue that molten steal, actually liquified steel, was found and of course that should be impossible.
But i dont keep busy with any of the sorts. All i see is someone trying to disprove that jet fuel cannot melt steel beams by presenting a piece of steel that is left in a solid state after heating it to a higher temperature than jet fuel could possibly burn.
Thus actually proving that jet fuel cannot melt steel beams. I'd just wanted to point this out. This man goes out of his way to proof the point he is trying to refute, and has the brazen arrogance to even insult other people, calling them idiots, while he just finished demonstrating how wrong he was.

thechosentroll (12/17/2015) [-] Also, the plane crashing into the building could be a contributing factor for why it fell over. Just a thought.

ubercookieboy (12/17/2015) [-] Exactly. You have a massively heavy vehicle parked inside a few of the buildings floors with damaged infrastructure.
If a building starts to collapse from the top then it comes crashing down onto the rest of the structure. You have a cascade of debris that is quickly getting heavier and moving faster.
The building collapses under it's own weight. Similar to a person breaking his leg.
