If it doesn't agree with experiment, it's wrong. Part II

And of course he needs to prove that a mechanism exists that can survive an aircraft impact and massive fire for an hour and still leave the explosives viable.
 
In the slo-mo, you can see the right wall of the top section break completely loose after having dropped less than it's own length; from then on, it descends at free fall acceleration. It reaches the ground first, but barely ahead of the internal collapse front.
The core and the left wall zig-zag down with some delay after all floors have rushed down, while the right wall is pushed outwards by falling floors, and its lower habe topples over.

This simple model shows a number of features of the real WTC collapses:
- Floors falling ahead of columns
- Floors collapsing with an acceleration not far from g
- Wall peeling and toppling outwards
- Core failing last


FF, you're up.

You ignore lots of things, and here are a number of them.

Bazant wrote a series of papers. We have discussed four of them at length in this forum. Of these four, the first one was the one that NIST used as reference, and the second one is the one that talks about crush directions.

The first paper doesn't directly apply to the real collapse either. Bazant's strategy was: if it fails under the most favourable condition for it not to fail, it fails under any conditions.

Then he proves that it would fail even under the most favourable condition, and rests his case. He doesn't need to contemplate the real collapse case, because it's included under the any.

That's what NIST agreed with. NIST wasn't concerned with crush direction.


Did anyone bother doing an experiment to try to confirm their theories?

What paper explains the observed motions of out and down? Can you provide a link to it?

What experiment replicates the observed motions of out and down?

Was/were the Bazant papers peer-reviewed? Please post a link to the original paper, and the peer review(s).
 
And just as you asked for: It describes the cascade failure that occurred after collapse initiation.
Cascade failure? Is this your clever way of saying "pancake collapse"? That theory has already been abandoned.

You have asked me to explain C4. That is just one of many explosives that exist. I don't know of anyone who is claiming that C4 was used.

What you should be asking me to do is explain thermite, thermate, and nano-thermite. You can ask all you want, though; I'm still not going to discuss the issue. If you want to learn more, perhaps you could consult the ae911truth.org website.
 
Just ranting, eh?

We know enough. Engineers have designed buildings the world over using the findings from NIST.

The 9/11 CR wasn't tasked with technical stuff.

Your rantings don't change anything. The truth is what it is.

Are you saying my rantings are the truth? OK. Cool

It is true that engineers use findings from NIST, but doesn't mean their WTC7 investigation was complete or accurate.
 
No it hasn't. FEMA presented a pancake theory of collapse initiation. NIST dismissed that theory. FEMA also presented a pancake theory of collapse progression. That one is still in vigour.

ETA: NIST even makes a quick mention to floors pancaking in NCSTAR1, when they analyse the failure modes in the recovered steel.
The pancake theory was abandoned. There is no point discussing it.

What exactly did you mean when you claimed you never proposed CD and were embarrassed when your claims of CD were highlighted right here?

I am actually curious as to why you thought you would get away with that attempted dissemblance.
 
Proposal for an experiment to prove Cole wrong, Tomorrow when I have time, I will drop my 4 pound shop hammer, on a Mountain Due can.

Then I will Drop My 8 pound short handle sledge hammer on an identical can.

According to Cole and FF the motion and damage to the can should be exactly the same, since energy values and Scale do not matter.

What do you think the results will be?

The direction motion will be the same. The impacts won't be. Why would you waste your time doing this? Cole is not demonstrating impacts; he is demonstrating direction of motion. In your experiment, accelerations will be similar, the directions will be similar, and the sequences of the net forces will be similar, regardless of what two objects you drop on another.

NIST was supposed to investigate the collapses. They had the burden to investigate. They made claims. They have the burden of proof to prove those claims. In some cases, they have failed to provide the necessary proof.
 
Force will double with the 8 pound.
Will the directions of net forces be similar? Yes. Will the accelerations be similar? Yes. Will the direction of net force be similar? Yes.

Drop any object you want on any other object you want. The above will be true.
 
My first and last post in this thread.
Really?

OK. I stand corrected. The cat is out of the bag. I stand by my statements that were highlighted.

Controlled demolition is the only way to explain the motions observed during the collapse of WTC1 and WTC2.

If you claim CD didn't bring down the towers, then perform an experiment that proves your theory. I'm still waiting. Perhaps the reason there are no experiments is because there is no possible way to duplicate the motion without removing the support columns first, and the only way to remove the support columns first is to destroy them.

You can say Cole and I are wrong as much as you want. You are the one who is wrong until you can show an experiment that supports your claims.
 
AE911 doesn't even acknowledge half of 9/11.
They don't even talk about 50% of it.

Unreal.
Of all the absurd statements you've made, that may be the most laughable.
Do they need to talk about the hijackers? No. Do they need to talk about flight 93 or the Pentagon? No.

They only need to talk about the evidence which indicates the 9/11 CR and NIST reports are not accurate or complete.
 
Are you saying my rantings are the truth? OK. Cool

It is true that engineers use findings from NIST, but doesn't mean their WTC7 investigation was complete or accurate.

Your rantings can and never will come close to even resembling something that could be mistaken as truth.
 
Do you mean did anyone build a 94 story building and then drop a 12 story building on top of it?

Why would anyone need to do this? If you are performing an experiment to replicate similar directions of motion and accelerations, why would anyone need to do this?

Your argument is that no experiment would ever be accurate unless they built an exact replica of the twin towers. This is nonsense if your experiment only seeks to replicate the observed motions during the collapses.
