The 2000 degree melting tale is a lie. It's almost twice that. Suuuure it is, Bob. Got a source for that? Other than your typical conspiracy theory wackos, that is. Machinerys Handbook quotes 2500F as the melting point for carbon steel. The temperature at which it loses significant strength is a hell of a lot less. At 2000F, steel has gone an orange-red colour and is easily deformed, is non-magnetic as it has undergone a phase change to pretty much pure austenite. You *did* know that the WTC buildings had structural steel skeletons, didn't you? IOW, you're full of ****. As usual. Stick to fuzzy videos, every time you venture to present a fact on anything vaguely relating to tools or materials science, it's wrong. PDW He just posts this crap to get everyone going. When people jump at it, he has a vicarious moment in his home theater seating... Shrug. I skip most of it, not worth the bother. Occasionally he makes the mistake of posting something checkable in the real world. Then, it's time to shoot him down. Gotta haul the boat this w/end. Maintenance time. But never mind, I'll launch again right after winter solstice - the sun will be coming back my way soon :-) PDW |
