Since there was molten steel in ground zero, how does jet fuel melt steel beams?

>> No.9766160

Maybe the molten steel was there before the attack.

>> No.9766164

Maybe aliens planted the molten steel there to plant doubt deep inside us.

You know things can warp from heat without entering a liquid state, right?

jet fuel + kinetic energy from thousands of tons falling hundreds of feet turned into heat

They don't melt from warping.

How does that work and how does it explain molten steel falling from the towers before they came down?

Molten aluminium has a different color.

Also, jet fuel is unlikely to burn hot enough to even melt aluminium.

>> No.9766579

Dang I wish I still had facebook cause I went full autism one time on a family members post and spent a couple hours doing all the math and shit.

Basically it is very easy to bend steel when it heats, this doesn't cause melting though. The interesting thing about pressure is that on a load bearing beam like that the heat actually travels downwards into the highly compressed areas and aggregates. This can spike the temperature and destabilize the entire foundation of the building. This is part of what caused the free fall because the foundation beams gave way under the change in heat capacity and pressure. Jet fuel can't melt a steel beam, but it can transfer enough energy for parts to bend and deform under pressure.

Also aluminum has a melting point of ~660 C and jet fuel goes around 800 C

>> No.9766599

>>9766579
The jet fuel was not exactly in a controlled area where all the heat could be transferred. So actually heating aluminium that high seems unlikely.

Also, I know very well steel weakens when heated, however that is not the point. The point was the molten steel observed.

Although there was a steel frame building in the UK recently and it burned but did not collapse.

>> No.9766619

>>9766184
They didn't need to "melt". When the steel heats up enough to warp, that means it doesn't have the same loadbearing capacity anymore. A steel beam under no load will not warp until it starts to melt. A steel beam that is heated up to high temperatures will warp under load. The heat isn't what is warping it, the load is causing deflection in the weakened beam. Why is this so difficult for conspiracy niggers to grasp?

>So actually heating aluminium that high seems unlikely.
Aluminium melts around 660 degrees. A petrochemical fuel fire will absolutely accomplish that.

>The point was the molten steel observed.
Pics or it didn't happen. How can you even tell? Molten steel looks quite indistinguishable from molten aluminium when it's at a temperature high enough to melt steel.

>> No.9766636

>>9766619
He's referring to the molten metal described by rubble crews. The fires were brought down with the building and kept burning under it, so it basically became a giant furnace, or a series of them.

Where did you get that temperature from?

If there is aluminium at a temperature that would melt steel then there would also be molten steel, would there not?

>>9766619
I am asking where did the molten steel come from. Not whether fire weakens steel. How is this complex?

Not molten. Just weakened. There is a difference.

From your claim about molten steel.

>If there is aluminium at a temperature that would melt steel then there would also be molten steel, would there not?
Yes, if as you say there is molten steel, and therefore a high enough temperature to get aluminium to the temperature of molten steel, then we can conclude that there is molten steel.

But that's not the point. My point is, how do you know there was molten steel? Do you have a picture?

That is not steel. It may be aluminium, or some other metal, but it certainly isn't steel. When steel is hot enough to melt, it's bright white, not orange-yellow.

Artifacts of poor lighting and exposure-correcting cameras, that's what.

Do you see that slab of steel at 4:20? You will notice that it is solid. For steel to melt, it needs to be hotter, and therefore brighter and whiter, than that.

Info for blacksmiths contradicts you. It is yellow at melting point.

Also, that video was taken using a camera. And these pictures shown have also been taken with cameras, and tend to show the same colour as that video.

Pretty much all video and pictures show the same reddish yellow colour.

Regular thermite does it, but it needs to be shaped.
