weren't the steel able to withstand the hit of the plane? can someone answer me back. thanks

If you want to waste your time, go ahead. From your comments, it can be inferred that you were shoving logic, science, and engineering away and clung to your ardent faith that the buildings had to fall because of a controlled demolition. You have dodged many if not all all of my questions. Read everything I've said carefully, you'll find answers. Yes you can believe what you want but you were the one who started it by asking me to explain why I believed you guys were wrong and so I did.

You expected me to continue wasting my time. You acting like a child, side stepping questions, just to babble the same thing. You have right to believe what you want. So do I!

You are one to talk about growing up. If you really had no arguments left, realized you were wrong, or just wanted to ignore me then you could've stopped posting or said something else instead of telling me to grow up. I admit that I was a little arrogant, but you have now brought yourself to my level.

zvast (November 30, 1999 at 12:00 am)

Don't say any, because not everybody believes as you, including educated engineers. You are very arrogant, calling me or anyone backward. You have a lot of growing up to do. I think we are done here.

Uh, what are you trying to get at? Seriously, ask any Civil Engineer, ask ANY ASCE professor specializing in structural engineering, they will all tell you that fire raging at such temperatures for periods of times will affect the mechanics of steel. If you cannot understand this, then I'm afraid you're too backwards to reason with and I'll be forced to take back what I said about you not being like one of those 14 year old ignorant ass holes who make up 90% of the 9/11 conspirators.

zvast (November 30, 1999 at 12:00 am)

Yeah, sure. And it's happening all the time right?

delux48 (November 30, 1999 at 12:00 am)

I've also mentioned this (perhaps to someone else though) but steel doesn't have to soften, it just needs to deform or create thermal misfits. With fires burning at 1200F, 20 minutes is more than enough to alter the mechanical properties of steel.

zvast (November 30, 1999 at 12:00 am)

Also you skipped the fact about the size of triple box beam, 4"thick steel and the heat sink effect, that makes the time insufficient to soften such a thick steel.

zvast (November 30, 1999 at 12:00 am)

Thanks for lenghty explanation but "Once you get a good understanding of ALL of them" The problem is, his is not happening all the time. Buildings burned longer and did not fall. You also didn't explain the amount of kinetic energy needed, for very heavy (your words) metal pieces to reach WTC7 and do that much damage! The rubble would have to not only reach but have enough force to damage that large bldg.
