Could somebody give me evidence that friction causes molten metal?

[Hellbound]

people reported molten metal

how much heat could there really be? the fires fell 80 floors, have u ever kicked theembers of a bonfire? oops that sounds as bad as ur jenga theory

Not to mention that even in house fires molten aluminum and copper have been found, and molten or deformed steel.

It's not uncommon.

The rubble pile would have insulated these pockets of molten or partially molten material, keeping them at a high temp for some time (much as the underground coal fire that's been burning for a couple thousand years or so).

It helps to research these things, at least spend 5 minutes doing a google search and reading what experts have to say (such as fire safety professionals and fire department spokespersons) before declaring it to be "impossible" just because you never saw it on any of the CSI episodes.

the fire stop comparing cars to buildings, apples and oranges

From the fires? About 1.5 trillion joules. From the collapse? About 500 billion joules.

You really don't understand fire, at all, do you. By all accounts the fire was oxygen starved (embers aren't). Adding oxygen by vigoursly mixing in air would have caused the fire to increase in intensity, not decrease.

 

[delphi_ote]

nope. lots of ground zero clear up people talked about it

Lots of people say lots of things. Stop dancing. Show us who said what.

And do you mean metal or steel?

tell me how the fire increased in intensity when all its fuel was mysteriously pulverised?

Hearsay unless you back it up with sources/evidence.

 

[pdoherty76]

anyway if the fire was oxygen starved it wouldnt compromised the steel

You asked for evidence of friction melting steel. I provided.

You do not have a degree in physics.

Someone should have told these guys.

What does fuel being pulverized have to do with anything? If anything, pulverizing the fuel HELPS a fire, not hurts it. You are _really_ reaching now.

Why do you think we burn wooden logs, instead of wood shavings. Because it burns SLOWER. Try it yourself. Light a match in a room full of sawdust suspended in air... (that was sarcasm.. don't try it...)

Or coal dust (disclaimer: any painfull, lethal or non-lethal accidents following the lighting of a match in a room full of coaldust after reading this post is NOT my fault!).

Wow!

So all those grain silo explosions from dust were actually CDs!?

And I suppose that the old IM trick of adding flour to make a bigger boom, that's just heresay, too?

Wow!

Or try solid a chunk of aluminum and a solid chunk of iron oxide.. once nothing happens, try grinding them both up together in an industrial grinder (make sure the insurance is paid on the grinder, and the building, first)

pulverising the fuel helps, dispersing the pulverised fuel does not

are u suggesting that a desk thats burnig at 1000ft up will still be burning after its been crushed and dropped 1000ft?

erm isnt what u just described thermite?

so ur agreeing with the thermite theory

 

[Skibum]

pulverising the fuel helps, dispersing the pulverised fuel does not

If anything the fuel was concentrated into a big pile not dispersed.

Thousands of desks , many many many tons of paper, carpet, you name it all in a big pile that burned for quite awhile after the collapse.

Try reading. I'm proving to you that pulverizing the fuel helps oxididations reactions. Thermite is an awesome example of this.

I never said that it happened in the WTC. It's just proof that your idiotic comment about pulverization is bunk.

Here's a simple experiment you can do at home. Try running you car engine without oil. For more dramatic results, drain the radiator of coolant as well.

not a single desk was found
