Senior Research Scientist Proves that Planes and Fires Caused Collapse

Excuse me, bsbray, are you talking to me? or are you talking to Lyte Trizzle?

Because your question applies to both of us, right? But with that aside, I still want my numbers verified. Because if I remember right, for the longest time we had to argue that the towers fell too fast. Faster than gravity even.

Okay, then we got through that and then we went to they fell too straight. Too damned straight I tell you. And apparently we've gotten through that until now Lyte Trizzle has completely went the opposite way to..

they didn't fall straight enough - they spewed too big or something to that effect - never mind the fact you can only pile loose debris so high before it falls over itself - that's okay, we don't have to bring common sense into this.

But THIS...this error that Trizzle's expert found, well, now THAT that's important. So, I think the TRUTH MOVEMENT should publish the new resultant numbers of the equations used in Dr. Greening's paper, with the appropriate mass.

And I'll also get verification (or invalidation, so be it) of my work.

it is not you slanderous liar. it is me stating what greening admitted....that he questions his own conclusions and has come up with "additional" theories to help it out.



do it yourself.

why would i want to do anything for a person that calls me names, lies about what i say, and consistently accuses me of things i don't do.

if this site had any integrity you would be fired as a mod.

But not the momentum sweetheart, dear, loved one. And that is dependent on mg and we need that correct number...

from your expert.

Lyte Trizzle will be on a posting vacation for three days for falsely accusing me of a few things.

In the meantime, feel free to step into their shoes bsbray.

Please don't falsely accuse me of anything though. I have a migraine.

P.S. I'll attempt to run the numbers on Dr. Greening's paper with the "Truth Movement" corrected mass and see what changes.

Yes.

>.<

We weren't really getting anywhere productive, but if you want your figures for this or that or whatever then so be it. I don't mind, of course.

My honest concern is that that post that I just typed up is going to get buried and any points that it may have will just be totally ignored and overlooked just like so much relevant info around here is.


And another clarification of the symmetry thing:

The towers fell straight down, symmetrically, with the floors being blown out in all corners, all across the board, at about the same time (or at least within a ridiculously small time-frame that I've calculated and posted before somewhere). At the same time(!), the actual debris is being shot out laterally and the majority of it lands radially around the footprints.

That's how it went down; those are the facts of the matter. Make with the info what you will, but it isn't contradictory (given that Lyte is presenting the info as stated above - I'm not really keeping up with the convo between you two).

Well that sux. I think you gave him what he was here for.
Now he can claim that he was censored by ATS for revealing too much of the truth. Makes for great credentials.

Heh heh heh...just look at how MAD that smart lady has made you. Watching you degrade to the "she's picking on me" argument has made my day.

Of course I like the deflection away from talking to this "expert" of yours.

I'm forced to make the theory that you have no such "expert" available to check the numbers it seems. If my theory is a solid as Jones' then I must go on with speculation (as you have said to do), and speculate that you don't know what your talking about.

Of course, that's just following your logic.

I'm sure by now you are planning to say I am inappropriate too. Certainly has been your pattern in result to direct questions. Oops...sorry. I just "added" to my original theory.

Yeah, but the record will be here when they get back, so that spoils it all.

brsbray I have questions (I read your whole post)

Don't you believe that the collapse time is paramount to your argument? And don't you believe that this "error" that the TRUTH MOVEMENT has brought out could actually work to bring the collapse time to a more realistic time relative to the progressive collapse theory?

[edit on 1-29-2006 by Valhall]

I don't think that the plane/fire damage should have resulted in any collapse, period. Unless I'm convinced of otherwise (namely that there was enough structural damage to even initiate a collapse), I don't really care about the times. A ten-hour collapse would be too fast for me given the above, especially if it exhibited all of the other collapse characteristics seen on 9/11.

'My argument' is more focused around the lack of loss of energy during collapse, which is independent of the collapse times, and the lack of evidence for sufficient damage to the structure preceding collapse, etc. So, no, I don't think the times are paramount. I just think whoever did the paper that is thread is based on left a lot of important stuff out that renders the paper worthless.

Was that the only thing you wanted to address?

I may be wrong but wouldn't the energy increase?
I mean as the building collapses wouldn't the additional weight of each floor as it collapses add to the energy?

mass times velocity equals energy right? After adding enough mass to the initial mass from the top floors collapsing , at some point the resistance will be dwarfed by the ever increasing energy.

bsbray,

Well, you're looking at it from a different viewpoint than me, so I see how the collapse time isn't really important to you (other than it being a collapse time that would be way too short - and then it would take more than just explosives in the building, it would take divine intervention!).

I see where you're coming from. As you well know, because I've stated in several threads and even done a very conservative heat transfer analysis, I believe the damage was sufficient to cause collapse. And I do believe once any floor around 20 to 30 floors down from the top collapsed, the impact energy would be sufficient to cause progressive collapse.

Ultimately, this is going to take a Cray crunching an exhaustive model to tell us. And then we'll still be arguing about details, but slowly (I personally believe) we'll whittle away at each factor (and one will fall your way and one will fall my way - and my way is not based on trusting the government by the way, it's just based on physics - that's actually the ONLY contention I have in this whole thing that everybody try to take into account the physics) and one day all the factors will fall out and the majority will fall on one side.

While we whittle our time away on these physical points, I hope we continue to look at the information gaps, the anomalies in the official report, and the outright lies in that same report.

Because those - to me - are the voices of people gone crying to help us know what really happened. That's what's important to me.

(That and I want to validate my collapse time. HA! )

[edit on 1-29-2006 by Valhall]

Yes it would, but what brsbray is saying has some merit. It wouldn't increase linearly (say, take the mass of the floor and add it as each floor collapses) because you've got the maximum limit to a self-sustaining pile of debris you have to take into account. So as each floor collapses, you're going to lose material (as the videos show) due to the pile of loose material not being able to sustain its own height.

Speaking of information gaps, here's something I'm curious about.

AgentSmith, at 29-1-2006 12:52 PM, on page 3 of this thread:



Emphasis mine.

And then Lumos, at 29-1-2006 12:55 PM, on page 3 of this thread, underneath Smith's:



Notice that on two subjects, EMR's and megalomania, Agent Smith jumps the gun and responds to Lumos's post before Lumos even posts it, by a whole 2+ minutes.

All I have to ask is, "wtf?"

And I'm just waiting for someone to point to the edit Agent Smith made, because I happened to take a screenshot before the edit, with the exact same problem.

In addition to Val's post, consider that the amount of mass lost was actually a majority, as attested by the fact that most of the debris landed everywhere around the WTC site but in the footprints. Watch videos of the collapses and the same fact is supported yet again. Somewhere around 80% of the mass of the towers was thrown right out, and was not added to the falling weight. And the caps of course deteriorated as well.

[edit on 29-1-2006 by bsbray11]

Actually, I'm glad you brought this up, because in that thread, that happened more than once. And what I mean by that, is that lumos's post were also showing up before my post, when I posted before him. It was like they were logging into the thread with some type of delay.

It happened several times in that thread. I was in it posting and watched it happen. It was, indeed, weird.

This is off-topic, so many another thread is appropriate, but it's the first time I've ever noticed it anywhere. Somebody really should look into it and figure out what's up, because if it's not a forum problem, then somebody has some trojan stuff going on, and 3 minutes is a decent chunk of time. I would think a connection would time out before then.

I'm going to let SO know about it and see if he can tell anything. It's probably not going to be very fruitful now that the posts are static, but who knows.

Ok, even with the flying debris calculated (on the high side IMHO) then the seemingly accepted number for weight of WTC 1 or 2 is around 300,000,000 Kg divided by 110 = roughly 2,720,000 Kg per floor then subtract 80% to arrive at an added 544,000 Kg's additional momentum per floor for each floor overtaken in addition to the total weight of how ever many floors were above the original collapse point.

I'm not aware of any office building structure made to withstand that type of energy nor even act as an impedence of any appreciable manner.

Can someone please point to any hard data that such a structure exists anywhere? (office)

In buildings I've worked in (both concrete pan and metal deck) we're concerned where the loading goes on items 1000lbs. and up such as UPS systems, safes, fire proof files, law libraries etc. to keep within floor loading limits. I am told by structural that we have a 200% safety factor on concentrated loads but thats it, even then they have to be carefully located over beams near columns.

I am reasonably sure that a 1.2 million pound load dropped 12 feet onto any standard office structure would crush that structure as it were not even there due to its moment of energy.

Since I work with a bunch of strutural people, I'll ask their opinion about this type weight at even a small travel of 12 feet would do to a standard office structure.

I am very skeptical that 80% ejecta is even close to the true figure and agree with Valhal that a little common sense is in order. Visually the videos can not be relied upon for this figure most of that is a dust cloud of very much lighter weight particles - is there any expert evidence to support 80% or is that just a non-expert opinion formed from watching the video.




[edit on 29-1-2006 by Phoenix]

With that paragraph taken out of context is does appear that way, however you notice that he isn't leaving it at that assumption. He clearly states that he goes into it in depth in section 4.2. In that section he actually calculates the value for E1.



So as you can see he is not just guessing or lying about the value for E1. In fact he is breaking down his position peice by peice to fully account for all of his figures something completely lacking in the Jones paper.


Now I'd like to address your four problems with Greenings conclusions.



Where does this 80% of the mass figure come from? I would agree that 80% of the debris was ejected outward. However the steel, which was most of the mass, ended up in a huge pile at the base of the towers.

[IMG][/IMG]

So while the floors did not stay completely intact, that mountain of steel shows that the mangled steel did infact contribute to the mass of falling materials.



See my response to your first point. While debris was falling off, mass was still being added to the collapse through the steel.



Well, if both your points are incorrect assumptions, then no this cannot be assumed.



How does the collapse speed not slowing immediately indicate that?

As you can see from the graph Greening made from his figures the resistance is readily apparent.



Starting at the same speed and then slowing is exactly what we should expect from the resistance as the collapse proceeded.

It seems to me that what you are presenting is totally unrealistic, and did not happen.

Sorry Bsbray.

That additional weight is not equivalent to a unified force of the same weight, but is scattered and fragmented, so it should really be equivalent to even less than 544k Kg's.

Sort of like dropping 50 pounds of gravel onto a car compared to dropping a 50-pound rock onto a car. Which would do the most damage to the structure of the car? (Hint: it wouldn't be equal.)

And remember that the buildings' safety factors don't apply to one floor and then go to 0 for each floor afterwards. I use floor as a unit for simplicity, but the columns weren't set up floor-by-floor, so I hope I'm not contributing to that ongoing misconception.



Is this what they're saying? Because there was no unresisted 12-foot drop in either building.



The figure was actually derived from the amount of debris (in weight) located within the footprints, vs. the amount of debris located without.

It shouldn't come as any surprise if you've seen the photos of Ground Zero:

I think the actual 80% figure is from researcher Jim Hoffman, which he uses, though he's also said it was along the lines of 80 to 90 percent. Either way, there was obviously a very large amount of weight that was not added to the falling, "driving" mass (the caps, which were in themselves disintegrating), and even the weight that was added was fragmentary and could be easily deflected by intact beams.
