Could somebody give me evidence that friction causes molten metal?

[Lurker]

friction produces heat, i would like to see a circumstance where friction produced the 3000 degrees required to melt steel

First: The melting point of steel is 1000 degrees centrigrade. Not 3000.

erm i was talking fahrenheit

Um, it doesn't take a physics PhD to convert Celsius to Farenheit yet you muddled that too.

1000C = 1832F, which is nowhere near your 3000F claim.

would you like to put that quote in context? the fire man was making the poin that he was so amazed that that was the biggest piece he found

would you like to put it in context?
That was the biggest piece of a phone (that's shortened English for Telephone, BTW) that he found
How big a chunk of plastic/Bakelite do you expect to find after falling 7800 feet with a building on top?

Ah, give him some leeway. It is over half way to 3000.

Since the temperature of the brakes can reach around 1200°C in a typical braking event, it is obvious that effective brake cooling is a critical factor in maintaining brake performance throughout a race.

"Most steel has other metals added to tune its properties, like strength, corrosion resistance, or ease of fabrication. Steel is just the element iron that has been processed to control the amount of carbon. Iron, out of the ground, melts at around 1510 degrees C (2750°F). Steel often melts at around 1370 degrees C (2500°F)."

id say 2500 is close

why are u lot lying about the melting point of steel?

why are u lot lying about the melting point of steel?

I know you've said you only type with 1 hand for issues of speed/convenience, but I not sure what you're trying to ask here.

1) Why are you lying a lot about the melting point of steel?

2) Why is your lot lying about the melting point of steel?

3) Why are you not lying about the melting point of steel? (assuming a minor typo)

Is it perhaps one of those three?

Why are you guys lying....

It's a British thing...

Having had a class in metallurgy, I concur that there are various types of steels out there with various properties.

Lurker

P.S. Am I off ignore already?

 

[CENOBITE]

have you ever taken a ball point pen and chew on the end? It tends to get hot... not from your mouth but from the friction caused by torqing the plastic. Now appy pressure to steel and you get the same result... heat.

Lying? No. Remembered it wrong? Yes. I made a mistake on the melting point of steel. See? I admited it.

Now let's get back to the discussion at hand, shall we? You asked for evidence of molten metal by friction. It was given to you.

You were also told that not all debris were "pulverised".

Not to mention that it would not be impossible for a fire to burn in a sealed off space prolonging the heatexposure to the metal.

You were also asked for credible sources and/or evidence of molten metal being present at the Pile. Now, I may have missed it, but did you provide said evidence?

So, 2 then, kind of? Then I guess I can't answer his question until I get additional information. Who are these "guys" that are lying? I seen one guy make a claim about the melting point of steel, another took that number ran it through a simple formula to produce another. Finally, I came along, took the that last number to make a bad joke with regards to his original claimed number. Instead of claiming he was speaking of Fahrenheit instead of Celsius when the original claim was made, why not simply point out the melting point of steel in Celsius. The other way just looked like a dodge, which makes good fodder for jokes.

 

[The_Fire]

I seen one guy make a claim about the melting point of steel, [snip]

And now admitting that it was wrongly remembered which is not a lie.

I would like my appology now, doherty......

Oh, and it would seem I was wrong about the gender of the claim maker.

The crank shafts of car engines are made out of steel. If you run an engine without oil, it will get hot enough to melt the shaft, welding it to the case. I have seen it with my own eyes and I have provided a link that shows it.

crankshafts are not lumps of steel falling, apples and oranges

Don't move your goal posts. You only asked for "evidence that friction causes molten metal?" Remember? I don't think I've seen where you produced evidence that there were, in fact, lumps of molten steel, and, should they exist, that they couldn't be explained in a number of ways. Perhaps I've missed it though, I don't stay too caught up on the CT threads.

Don't worry. Happens alot "outhere" . I'm still waiting for the apology from that guy calling me a lier thou........

 

[Anti-sophist]

You are right, it is apples and oranges.

The steel at the bottom of the WTC was under a great deal more force, and absorbed a great deal more energy than a crank shaft in a car w/o oil.

another goalpost move

"can friction melt metal" becomes "can friction melt steel" becomes this, lol
