Hardfire: Physics of 9/11

[aggle-rithm]

.
If you don't know the distribution of steel and concrete and don't understand the conservation of momentum.

Or if you WATCHED IT HAPPEN ON TV.

There's no reason to make it more complicated than it is. Airliners crashed into the buildings, they caught fire, they fell down. No mystery here, unless you are so obsessed with hanging onto a tiny shred of your preconceived fantasy that you'll do anything to confuse the issue.

Also one that involves ODE's. I don't think many truthers can solve those.

Does anyone know the location of an online version of:

The New York Public Library appears to have this in the SIBL branch (not online). I'm interested in seeing it, too. If I get a chance, I'll stop in if someone doesn't come up with it first.

Do you mind if I add a bit?
Airliners crashed into the buildings, they caught fire, they fell down and many reasonably competent structural engineers can explain how and why they fell down.

I really don't think you'll find one. That's a regular subscription-or-fee-only Journal.

I have access to that Journal if you just have questions about it, but I won't be infringing their copyright...

That's a real Journal, where you pay to read it, not pay to publish in it.

My access won't allow me to view articles in the International Journal of Impact Engineering. You may be able to find a University student in this forum that may be able to help you, I'm not sure? Using Google Scholar I see it's available from Science Direct for $31.50.

I'm not sure, but this may be helpful.

 

[Mel Odious]

This is what I was able to turn up.

Don't know if it's what you guys are looking for or not.

Thanks! That's the paper I saw ages ago and have been looking for ever since.

 

[R.Mackey]

Thanks! That's the paper I saw ages ago and have been looking for ever since.

Yeah, that's the "first principles" paper Dr. Wierzbicki put out with his students early in the investigation. It falls short in several areas, as any simplification will, but it's a very good example of making simple models to estimate behavior of complex events.

... meaning it's practically on topic! Hokey smokes!

They say the fabric of the CT universe is sewn with derailed threads

 

[Toke]

Just to clarify I said - "Your mass and stiffness is seriously not to scale"

1/11Hz versus 1Hz?
Just thinking of a pendulum got me laughing at the scaling problems psikeyhackr is facing.
(or facing avay from?)

 

[alienentity]

Ryan, perhaps I'm just stating the obvious but this thread isn't really a conspiracy topic, it's just a straightforward engineering topic.

Maybe that's why you're getting so many inadequate responses. I'd be interested to see the models competent engineers could come up with....too bad there are so few (if any) in the 9/11 truth movement.

Happy hunting though....

Re: the Wierzbicki paperThanks guys. I don't want anyone to pirate the paper.

I'll dorp a note to the Professor & ask him if he'd consider dropping me (us?) a copy. I'm sure he'll be pleasantly surprised (shocked?) that a bunch of people are discussing it.

I'll let you know what he says.

I hope your NWO paycheck is huge this month, psikey. You're doing a fabulous disinfo job bringing the 9/11 CT cause into such disrepute.

GlennB?

Glenn Beck?

I'll make sure he gets a little extra.

Here is a video of a structural engineer discussing mass distribution:

I'm wondering why some of you believe the distribution of mass is not an issue for the twin towers, yet these engineers find it quite critical for their design?

Who, exactly, are you referring to in the above?
