How can a falling body could go into free fall in spite of having to use some of its gravitational potential energy to overcome resistance in the process?
And this is where you're wrong dumbass.
Well, the answer to a question would be right or wrong, not the question itself.... dumbass. Since there was no answer to the question, it simply remains an unanswered question.
What was providing the resistance below? Show me YOUR calculations and drawings that prove that the eight floors worth of REMAINING/DAMAGED structure could provide enough resistance to slow the load of the remaining upper structure.
See? Right back to focussing on me. The calculations governing this scenario (WTC 7) were carried out by Isaac Newton centuries ago you fool....
F (force) =
M (mass) x
a (acceleration). I asked you how a falling body could go into free fall in spite of having to use some of its gravitational potential energy to overcome resistance in the process, and you, using your single brain cell, respond by demanding I provide calculatons verifying Newton's conclusions! The only way free fall can occur is if there's no mass in the way offering resistance, and there can be no mass in the way for the entirety of the duration of the time it occurs or the fall time will not be the same as a free fall time where there is no mass in the way. That's what Isaac Newton said.... not me. You're insisting that despite there being mass in the way (eight stories of a steel frame building), that some peculiar never before seen process of progressive structural failure briefly created conditions that somehow allowed the visible upper portion of the building to fall as if through air for over a hundred feet. You are in disagreement with Isaac Newton on that, and it is therefore up to you to prove an exception.... not me.
Can you? Is this why, after 12 years not one single architect or engineer has been able to provide this proof?
It's not rocket science (well, maybe to you it is). The building collapsed. There was mass in the way. It went into free fall. Hence.... The mass in the way must have been removed by some external force because there's no other way free fall can occur. Google "Isaac Newton" if you don't believe it or can't understand it. Any equation I or any one else does, or has done, or can do to "prove" it would only be a restatement of Newtons well known observation....
F =
M x
a.
The problem is your lack of structural knowledge. You are trying to debate something regarding a subject that you have know working knowledge of.
I know, I understand nothing and you understand everything. I'm an asshole and a liar, I'm a coward and a thief, I'm a (now confirmed) twoofer, I don't brush my teeth often enough, I sniffed my finger once after scatching my ass, I peeked through the bathroom door keyhole when I was a kid and saw my (really hot) Aunt Hazel naked, etc., etc. Whatever man. I've already heard all that. Doesn't help your argument, doesn't prove an exception.... clown.
Do you understand that a structure is comprised of many components to function as a WHOLE, as one unit?
No, I thought it was all made of styrofoam.... Doesn't help your argument, doesn't prove an exception.
Do you understand that when you weaken/damage/fail certain parts of said structure, the structure as a WHOLE (as it was designed) is now comprised and cannot FUNCTION as it was designed?
No, I thought weakening structures became stonger as they got weaker, and weaker as they got stronger.... Doesn't help your argument, doesn't prove an exception.
If you start removing components, the the load on the remaining components increases. There then becomes a point in time were the REMAINING structure will reach a point of ZERO RESISTANCE. You're too stupid to figure that out though.
On the way to any point of zero resistance in any progressive structural failure, the failing component will still be resisting the load as it fails, it doesn't just go from 100 percent to 0 percent (unless one uses dawsian physics). As the severity of the failure continues to increase over time, the component will resist the load less and less, but no progressive structural failure can have the same fall time as an object falling through air.... clown.
What caused the ENTIRE roofline to start it's descent as shown in both NIST's and Chandler's graph?
I don't know.... What do you think? Maybe Roy Rogers used his lasso on it, maybe Superman was banging Lois Lane in the basement and got a little excited.... Or maybe it took a moment for timed explosives going off in rapid succesion to completely remove the supporting structure. I kind of like the Superman scenario.... Doesn't help your argument, doesn't prove an exception.
There is a point BEFORE the freefall that the entire roofline is moving downward at less than freefall. What caused that?
Maybe Superman wasn't quite finished yet and just kind of held up the building until he was, then he grabbed Lois and flew away so fast nobody saw them. Yeah, I think that's how it went down man.... Doesn't help your argument, doesn't prove an exception.
Are you afraid to answer that for some reason?
Well, at the very top of your last post you quoted the question I've been asking right from the start before launching into a bunch of horse shit and focussing on me instead of the topic again.... Looks like you're afraid to answer that for some reason.... clown.
