What stops a collapsing structure that has a big open space inside from having a part "free fall" as it is collapsing??? (Nothing.)
Therefore, that structure "free falls" for a brief moment.
Meaning the kinetic energy is still (theoretically) doing work. Obviously it wasn't, but that's what you need to explain at any rate.
I believe that NIST did explain the collapse, and also the free fall portion of it. The problem is when people have already reached a conclusion based on "you tube" partial video evidence of a brief part of the whole process.
As I have mentioned before, all of the collapse took more than 15 sec.
You can´t neglect what was happening to the structure for the first 6 or 7 sec.
Free-fall = no kinetic energy loss = no physical work being done by the kinetic energy itself.
Please elaborate on this...
How did you determine these simple equation???
How did you come up with "no physical work being done by the kinetic energy itself???
So how was the building "collapsing" in on itself without doing work?
Same question as before. Please explain.
I only explain this to you now so you don't have to wonder in the future how you could have been so blind to an obvious demolition staring you in the face.
If demolition was "SO OBVIOUS" we wouldn´t be having this discussion.
A lot of evidence would have been found, that could not be hidden.
It has been explained by experts in the field. Which I dare to say you probably are not.

Just so we're clear, do you know what units work are measured in? And kinetic energy? Are you familiar with this stuff at all?

Please enlighten us with your knowledge and expertise.
Thanks.
eutectic reactions,

You use the term "eutectic reactions" quite a bit, as if this is some sort "smoking gun" or suggestion of EVIL forces, that caused WTC7 and the other towers to collapse. But you know its funny, you really dont know the proper use of it, nor do you use a little something called research and critical thinking.
Yes, NIST mentions eutectic material on some steel samples. Of course, it is there, I do not deny its authenticity. However, you are trying to twist it into some sort of twisted idea that it has SOMETHING to do with therm*te or something planted, etc etc etc, and this is the problem.
I have pointed it out many many many times in the past, hell posted pages of facts, theories, and ideas on what caused it and how it PLAUSIBLY could have come about. Yet, you ignored it every time because it just doesnt jive with your ideas.
The eutectic mixtures found on the steel point to what happened well AFTER the impacts and collapses.
You forget the fact (or ignore) that the pile of debris was smoldering for weeks. I have posted countless times the many chemical reactions that would have been present in the pile, including the processes that more than likely contributed to the eutectic mixtures found. Most of it has to do with oxidation, and none of it has to do with magic therm*tes.
A little research into oxidation and chemical reactions that can create such effects give a better understanding and explanation as to why some steel pieces showed the "eutectic" materials.
Instead of trying to paint this eutectic material as PROOF of something sinister, how about you do the proper thing and explain why no way in hell it can't be anything else more mundane than your standard oxidation process of the steel when its exposed to high temps for a long period of time.
Its a little something called the scientific process. First you go through all the most plausible explanations first, then when the plausible ideas and explanations are exhausted THEN you start to dive into the more "out there" ideas when the other plausible ideas dont fit or are just too unbelievable. You have completely ignored the plausible explanations.

According to you only. Neither FEMA nor NIST state this absolutely as if it's a fact. They simply say these are possibilities and were unable to determine the exact cause of corrosion, specifically the corrosion FEMA analyzed in appendix C of their report.
So count that as one reason I don't listen to your gospel. It's not factual.
There is nothing "magic" about adding things like sulfur to iron oxide and aluminum to make it a eutectic mixture. If there is, I'd love to hear what exactly is so "magical" about it. Next you'll be calling the law of conservation of energy "magic."
What "high temps" corrode steel in the same way as a eutectic reaction? Will you cite a specific temperature, or admit you're lying?
My guess is that your next step will be to back-pedal on this and try to cover your ass with some other excuse.
You have yet to give a plausible explanation.
Soon you'll be telling me all the sulfur in the mixture came out of the drywall in the buildings without being able to explain why the rest of the drywall wasn't there, or how it got out of the drywall in the first place to enter into the mixture. I have heard all this jibberish before. Like I said, you have yet to give an alternate explanation that is plausible.

Well first of all that is exactly how something like that will happen. Addition of sulfur to HEATED steel will cause the melting point of steel to lower significantly. Also oxidation itself also creates heat. Corrosion of steel produces heat. nothing magical about it.
One likely reason why NIST and FEMA didn't bother going any deeper into the subject is because it is moot to the overall investigation of what brought down the towers, not what happened to the steel weeks later.
i already explained many times how that all works, but yet, it never sunk in i guess. Lordy lordy, I wish I had a nickle for everytime i have posted how this whole thing works. I'll give you the abridged version then: You have heated steel beams. Heated steel beams oxidize more rapidly than cold steel. Oxidizing steel beams also produce heat. In large piles, iron and steel oxidizing can create a lot of heat. Sulfur added to heated steel will lower the steel's melting point.
Oh gee, where the hell else would sulfur (FOUND MOST COMMONLY IN DRYWALL) come from? It boggles my mind how one can be so ignorant to facts, and cannot use some basic common sense skills and research beyond the conspiracy sites.
Its called decomposition of drywall. All those thousands of pounds drywall getting crushed to powder makes for a really nice set up for quick decomp when wet and heated.
I know its all jibberish to you, but then again, I guess simple chemistry can get a little overwhelming when you have zero knowledge of it. I guess to you, sulfur must be added in solid form to be able to do what it did to the steel. That is not true. Sulfur reacts in different forms and is released in different forms. Not my fault you dont understand it.

Actually, alkaline earth sulfates, at temperatures of 400-500C in the presence of carbonaceous materials will reduce to the sulfides. This could be a source of sulfides that would form the eutectic mixture.
Originally posted by bsbray11
It could be a source of the sulfides without considering additional information from appendix C of FEMA's report, but it does NOT account for the eutectic mixture. The eutectic was not just sulfur. Nor was it sulfur and steel/iron. It was more specific than that, and also included high amounts of copper and smaller spikes of certain other elements.
And steel does not turn into an instant eutectic or thermite reaction by itself just because you elevate it to a certain temperature. There are still specific conditions that must be met for thermite/eutectic reactions to take place, and just having a hot piece of steel with sulfur on it is not such a condition.

The manganese and copper were in the alloy used in construction. The amounts were small. The elements identified by EDAX were the various iron, copper, manganese, sulfur and oxygen.
One sample, location 1 figure C13 also showed a nice Calcium peak, suggesting that CaSO4 may well have been the source of the sulfur.
Thermite is a mixture of iron oxide and aluminum; there is no elemental iron, or steel, in it at all.

You do NOT have any evidence, only speculation and conjecture, that that's where the sulfur came from.
That peak [calcium]is still small compared to the sulfur and iron peaks, and calcium does not consistently occur with sulfur in the samples, suggesting it was NOT the source. Calcium is the 5th most abundant element on the Earth's surface, and like I said, there is no relationship between high amounts of sulfur and high amounts of calcium. They don't occur together and the levels aren't consistent, either.
