re: People claiming that obamacare will implant RFID chips
you're making this question a lot harder than it needs to be if I were to drop a ball at the same time the towers started to fall it would be a tie how is that possible with the pancake theory

No. I'm not. It's a simple question, actually. If you're going to believe in this "pancake theory" you'd better know how long it takes a column to fail. Otherwise you're just speculating based on something that "sounds good".

How is it NOT possible? The time it takes a column to fail approaches (asymptotically) 0 seconds. As soon as the floor below is overloaded by the failure of the columns above it, it fails. As soon at that level of columns fail, the ones below it fail, 0 seconds later. As soon as those above it fail, those below it fail 0-seconds later. Repeat X times. There is no appreciable decrease in speed.

I'll grant you we're idealizing the 0-second failure time. In realty it's probably something like, say 1/1000th of a second (I'm being generous). Given that there were (say) 103 floors in the WTC that would have made less than .1 second difference in the "fall time" of towers.

No way you can measure that accurately from a video of the accident. Too much dust, too much debris. You'd have to track a single point all the way down to even get close. Especially considering video runs at 1/30s frame rate, and drops every 30th... you're talking about the difference of +/- one frame of video.

Sorry. Physics aren't on your side.

re: People claiming that obamacare will implant RFID chips
there is a resistance in every floor. the top 20 the 15 percent of the building is falling through the bottom 80 percent of the building and encounters no resistance whatsoever?

the speed of gravity is the speed of gravity I don't care if it's an apple and orange the only factor Is wind resistance but that's not the case in the World Trade Center fall

and another thing if the melting theory that you talk about is true the top of the building would fall to 1 side not straight down.

there is no way you are a structural engineer no way.

I'm out I'm done

No. There isn't. Once a column fails it provides NO resistance. And since it takes no time to fail... there is essentially no difference between sequential failure and free fall. It's simple physics.

You should care. Because you're apparently just parroting what others say, rather than knowing what you're talking about.

No it wouldn't. The table I posted shows how much strength steel loses as a function of temperature. Steel will lose over half it's strength before reaching 500C. If you can't understand that from the table I posted, you should try to learn more before buying into any more theories.

The building would NOT fall sideways. It's ignorant to think it would. To fall sideways it, several things would have to be true. First it would have to fail first at the bottom, rather than the top. This is clearly not the case.

Second the beams of the structure would have to fail before the columns. This is never going to be the case as columns are inheirently weaker because they don't fail in bending.

Finally, one would need a force applied to the top in the sideways direction. There is nothing pushing the building sideways.

If you believe in the "pancake theory" you clearly believe that the building fell floor-by-floor. That would mean it would fall vertically by overload of the floor above. Clearly this is the case.

Failure of the columns by heat has nothing to do with with the direction of collapse, though I'd love to hear your explaination of how it could.

Clearly you aren't either. Do you even know what Castigliano's Theory is? Tell me do columns fail in bending? Do columns yield before failure? Or do they fail all at once -castastrophically? You're right, tho. I'm not a structural engineer, I'm hold a ME degree. But all of the above are basic engineering concepts that are taught to civil and mechanical engineers in sophomore year. It's pretty clear you're no structural engineer either.

Thanks. You've proven my OP.
