At this point, the only thing any rational person could conclude is that you refuse to try to understand.
Just because a mathematical model shows that in theory something strong can be destroyed if it's hit with enough energy, it doesn't mean that any amount of damage can be caused in any impact. It's not reasonable to conclude from the model that the plane can't do other than "slice through the building".
Pure nonsense. The whole point of the model is to demonstrate the amount of momentum involved. The amount of energy imparted is sufficient to break core columns. Perimeter columns are weaker.
Reasonable people cannot fail to understand this. You are obviously unreasonable. You fail to accept that weaker cases are destroyed when energy suffices to destroy stronger cases. That is your failing, not Ryan's or anyone elses.
NIST is not the problem here. It's the slug of fuel model that doesn't cover different fuel distribution cases. It assumes that each broken column was hit by an average volume of fuel, when in fact a considerable section of each wing was empty.
Still haven't read the report, have you? If you did, you wouldn't have said this. Hint: Look for the section of chapter 10 where they describe the various differing fuel loadings.
You're misrepresenting the presentation by ignoring the conclusion that was drawn from it:
I'm misrepresenting the presentation to illustrate what is specifically, explicitly, unambiguously stated about it? All people have to do is look at
my post, post 1174, and see the explicit statements. "Simplified analysis of core damage"... "Demonstrates that, at this speed,
fuel alone can plausibly fail core columns"... it doesn't get any clearer, Bard.
We can't see the damage to the core columns, so he can only be talking about the perimeter columns.
Which is why Ryan presents a
mathematical model. Duh. When you know the characteristics of an object, you can create models based on those characteristics. That was the whole point of his demonstration: To illustrate simplified modeling. You missed this point by such a large margin that no one reading your posts can fail to see that your only objective is to misrepresent Ryan's presentation.
The exercise completely disregards the wing, so he can only be saying that it's credible for the damage to have been caused by fuel alone.
If he wants to include the wings, then the wings should be part of the exercise.
The wings
add mass and are the carrier of the fuel. But again, Ryan's point is about the amount of momentum available, regardless of how it is carried, and that it's sufficient to destroy the strongest elements: The core columns. He's explicitly, unambiguously stated this. His data is taken from a report that states this. His math uses values based the core columns and the calculated momentum. The only reason you're making the arguments you do is because you cannot challenge the math. You cannot show that the fuel has insufficient momentum to create damage. You haven't even tried. You haven't read the original data, you haven't tried to comprehend the point of his presentation, and you've drawn up a nonsensical argument to give the appearance of debate. There is none here. You've not presented a case that negates Ryan's.
Until you can take his math and show an error, or unless you can show that the properties of the columns that NIST provided and Ryan used are incorrect, then
you have no argument. None. Zero. If you want to salvage anything from your point, then either show a math error on Ryan's part, or show that the columns properties were different. Anything else is blowing hot air, and you've done enough of that.
Don't bother replying to this unless you can show math errors or show that the properties are other than what NIST said. There's nothing else to argue, and you've been corrected enough times already. Unless you post something pertinent to either of those, you will not get any further responses. The most I'll do is bump old posts if I feel like it.
