183. I wasn't talking about WTC7. I was talking about the towers.

And again, the problem is not the complexity, but the simplicity of the collapses.

One approach would be to see how many inputs of sudden structural weakening would be necessary to keep the collapse centered and "essentially in free fall" and then gradually reduce the number of those inputs to try to approach a model of a natural collapse behaving in that way.

As to WTC7, why not construct a model based on the theory that the collapses of the penthouses were achieved by cutting beams at the top of the building, and the building was then brought down by cutting core columns. Why not do it? What are you afraid of?

You're not demonstrating any competent grasp of anything. Ace Acme Dec 2013 #80

Your inability to see this is both amusing (at least to me)... AZCat Dec 2013 #81

I don't think you have a very good understanding of basic physics. AZCat Dec 2013 #98

Maybe you should try making your points instead of merely implying that you have one. nt Ace Acme Dec 2013 #99

My point is quite simple - you are wrong. AZCat Dec 2013 #100

Your "point" is an empty assertion. Ace Acme Dec 2013 #101

If you think it's that simple... AZCat Dec 2013 #102

I don't have any work. You need to show yours. NIST needs to show theirs. Ace Acme Dec 2013 #103

Again, your unfamiliarity with basic physics concepts is showing. AZCat Dec 2013 #104

Again you are showing your reliance on empty claims. Ace Acme Dec 2013 #105

Kinetic energy and...? AZCat Dec 2013 #106

Ah yes... zappaman Dec 2013 #112

Cardboard boxes are subject to the same laws of physics as everything else. Ace Acme Dec 2013 #115

gee thanks Abe. zappaman Dec 2013 #116

Nobody said they were the same. They are, however, subject to the same physical principles. nt Ace Acme Dec 2013 #117

That'd be the same physical principles you don't understand. AZCat Dec 2013 #119

No, you don't. AZCat Dec 2013 #128

I don't remember Tony Szamboti going this route. AZCat Dec 2013 #136

Nothing like cardboard for representational scaling of forces, huh? AZCat Dec 2013 #121

Nobody claims there is any scaling. It is a demonstration of principles. nt Ace Acme Dec 2013 #124

You've never done any study of scaling, have you? AZCat Dec 2013 #145

Scaling is not an exemption from the laws of physics. nt Ace Acme Dec 2013 #151

Of course, that's why you have to look at similitude. AZCat Dec 2013 #155

It's a demonstration of principles, not a model. nt Ace Acme Dec 2013 #158

Principles that rely on similitude. You're not getting it. AZCat Dec 2013 #159

It's a demonstration of principles that apply equally to cardboard boxes and buildings. Ace Acme Dec 2013 #160

Except for that whole square versus cubic relationship thing, of course. AZCat Dec 2013 #162

Square v. cubic affects the numbers. It doesn't change the principles. Ace Acme Dec 2013 #164

Huh. This isn't going to get better for you. AZCat Dec 2013 #165

They demonstrate laws of physics that apply to buildings thus as they apply to boxes. Ace Acme Dec 2013 #168

They really don't apply the same way. AZCat Dec 2013 #170

Nobody said they would behave the same. It's a demonstration of principles. Ace Acme Dec 2013 #172

I claim Gage doesn't understand the principles he was trying to demonstrate. AZCat Dec 2013 #173

To you a request that you back up your claims is a request for spoon-feeding. Ace Acme Dec 2013 #248

Of course not. The collapse was too complicated for diagrams. Ace Acme Dec 2013 #114

The collapses may have been, but your example shouldn't be. AZCat Dec 2013 #120

Let's just use NIST's free body diagrams as a point of discussion. Ace Acme Dec 2013 #125

Why wouldn't the NIST use free body diagrams? AZCat Dec 2013 #127

There's nothing sophisticated about not analyzing the collapse. Ace Acme Dec 2013 #131
