Some simple Tower 7 questions

Funny, I read this just after getting back fro mwork where we had to deal with a walk-in refrigerator door whose steel hinge snapped due to metal fatigue. The metal itself broke in half, not at a joint.

I know about metal fatigue, it takes a lot of bending. These joints only bent once

I wonder, does Christopher7=Christophera?

Concrete is poured arround rebar, not I beams
 
Steel bends and buckels. It doesnt just break off.[qimg]http://img140.imageshack.us/img140/4310/wtc7debris12xq8.jpg[/qimg]
Oh, Christopher 7!
Oh, Chris!
Hello?
You seem to have completely forgotten that we went through all this months ago. Remember my pretty pictures showing that the exterior columns on WTC 7 had separated at their joints? Remember, Chris? Remember my long posts here in this very forum?

You can see those pretty pictures again in the WTC 7 paper that's linked in my signature below. And read the paper while you're at it. You will be enlightened.

The steel used in swords is quite different than the steel used in buildings

Care to reassess your original statement, then? You didn't specify a particular steel, you generalized that steel doesn't break. Then you were shown evidence that it does. Will you admit to a mistake?

Ahem. The spot where the steel hinge broke was not a part that bends, but stays entirely rigid. Perhaps I used the wrong word when I said "metal fatigue", but the point is that steel does indeed break.
 
NO

Thanx for the closeup. Some of those could have broken at the bolt [or rivit] line if that is a bolt line. The bottom part is welded. Seens odd that they would weld the bottom half and bolt the top. In any case thats a very interesting photo.

The one i posted, on the other hand has been cut.

Strange that you used that FEMA picture to back up your first picture then, you did it in this post: http://www.internationalskeptics.com/forums/showthread.php?postid=2173948#post2173948

I assume that your cut column is the one that you featured in this post:


There's a lot of wide-angle lense distortion on those photos and the angle is really weird. I can see a ragged edge and it looks like it's at another weld point. Also, why only this column? There seem to be others that have broken at the same height.

This is NIST's current thinking on column failure:

Possible Modes of Column Failure:
  • Squashing (Yielding) of Column
  • Cover Plate Weld Failure
  • Failure of Column Splice
p28 of http://wtc.nist.gov/pubs/WTC Part IIC - WTC 7 Collapse Final.pdf

What makes you think that it was an acetylene torch or a shaped charge and not one of the above?

Also, if this is powerful evidence, why not take it to the world?

From another thread:

28K you're obviously not making much progress in convincing people here, but I don't understand why you're even trying. If what you're saying is, as you say, both obvious and scientific why aren't you making an effort to get this information out to the world? The world is has many media outlets, technical journals and engineering departments - why not send your information to people involved with these? If you don't manage to get the word out this way, I would say that you are ultimately insignificant.

Remember, this isn't about us convincing you, it's about you convincing the world. At the moment, the world says you are wrong. What are you going to do to change its mind?

No Gravy, i havent forgotten your pertty pictures or your long posts.

Thanx for the birthday 'card'. LC didnt rember my birthday so i decided to come back here for my fair share of abuse.
 
maccy

I trust FIMA and NIST pictures, their thinking, .......not so much

I'm gonna check out your ref.

BTW, one doesnt have to wait long for a reply here, i like that
 
I really, really wish the Loose Change forums would open up again.

You guys are totally lost without your own little world to trade recipes and anarchist gossip, huh? As Gravy said, we've been over this with you before. Nothing new have you brought. Gone you should be.
 
Wait... The LC forum imploded again? :eye-poppi

Boy, you can miss alot in three days...

Was there a secondary device?

Why do you keep writing FIMA? "E" and "I" aren't even near each other on the keyboard:confused:

The reason I mentioned it was because it looked to me like you were using a photo from a FEMA report as evidence of some sort of controlled demolition. Now FEMA and NIST say there is no evidence for controlled demolition. If they are covering this up, then why would they include an incriminating photo? The only answer must be that they aren't covering it up but are, as trained scientists and engineers, too stupid to recognise the evidence which is obvious to a select bunch of internet message board posters.

R.Mackey I enjoy your posts. We know you have been through all this with us before but we don't believe it. We aren't just being stubborn; we really don't believe you. Please try harder.

You say you want us gone, if we all go what is this section going to discuss?

The wall curves about the same as the beam FWIW
I see 2/3 straight edge with blue discolaration

and the beam behind it, same thing
These joint ties have been cut at least 2/3


Its behind this section

I am. This is part of the world.

Unless by "we" you are affiliating yourself with those who are regulars at the "Loose Change" forums, and supportive of that laughable bit of video, I'm not sure what you mean. I haven't run across you before.

However, you make the same mistake that many of the Sept. 11th deniers do, namely that of egocentricity. You see, I don't care whether you "believe me" or not. That's irrelevant. You are, presumably, a grown individual and responsible for your own education. We don't debate these issues begging, hoping against hope, for your approval. Since virtually every one of you believes in NWO mythology, demolitions that fly in the face of all known physics and logistics, or technologies culled from the scripts of Star Trek based a total lack of scientific understanding or logical thinking, it would be foolhardy for me to believe that I could convince you otherwise through rational investigation.

Indeed, it is not I who have to convince you, but the other way around. You can prey upon your fellow conspiracy theorists all you like, burning DVDs and advancing insane theories to your hearts content, selling T-shirts and hosting podcasts along the way, but ultimately this is self-defeating. It is you and your movement that desperately craves the attention of the general public. But to do so, you need to challenge the understanding, and the vast body of research that the scientific community has produced.

Except you can't do that. Here I refer to "you" in the same sense as your use of "we." Not you specifically. You yourself haven't even attempted to bring anything.

This isn't about belief, friend. You can believe any fool thing you please. But if you want your beliefs to affect reality, you need to do some more homework. It starts with a fresh acceptance that your preconceived notions are worthless, and only the evidence matters. Hardly any among your movement are capable of this, as seen in the continuing spats even at the highest levels -- Steven Jones vs. Fetzer, no-planers vs. everybody else, etc.

Can you do this? Do you have what it takes to be a scientist? Show me.
 
I haven't claimed to be a scientist which is why I appeal to the scientists to convince me. I don't believe parts of the official story and particularly the strange disintegration of tower 7.

I'm not a structural engineer and i'm sure they know more about builing collapses than me, but boy did it fall straight! Fire is one of the most random things that can happen to a building and so is random damage. I am yet to see how all this randomness led to what we saw

You will not be convinced because you have too much 'intellectual' investment in the CT to let it go.

If the CTers were to be honest with themselves (let alone the rest of the world) they would start to see how they have continually adjusted their thinking on the subject of 9/11 to meet every new debunking without giving up the core belief of it being a government/nwo/illuminatti/jewish conspiracy.

They don't seek the truth, they just seek validation for their paranoid world view which tells them it must have been a conspiracy because that is how the world works, and random chance/luck and coincidences make the world a much more chaotic place than they would like to accept.

For the woowoos everything that happens, anywhere and at any time, is the result of a covert conspiracy because that explanation gives them a bogeyman to focus on and blame for some other defficiency in their lives.

They will not learn or accept because the truth really is too painful for them.

Life is so much more exciting when you believe in conspiracies, especially when the conspiracy in question apparently does not actually require you to do anything to counter it.

Apart from posting on internet forum.....

:cool:

Whose fault do you think it is that you don't understand what they're saying?

And why should anyone care if you're not convinced?

Well, consider that the structure itself is not 'random' but is mostly symmetrical.

Why shouldn't a symmetrical structure collapse symmetrically after random damage?

If you understand that a structure is interdependant on it's various elements, in just the same way that the roof of your house is interdependant on the walls to hold it up and the walls are dependant on the roof restraining them from moving out of upright.

If the damage to a structure is great enough and the further weakening of that structure through fire is allowed to go on for long enough then despite the randomness of the damage the structure is going to act as a whole because that is what it is designed to do.

The priciple of redundancy takes this into account by requiring structures to withstand a given amount of damage before failure. But that doesn't mean they can withstand ALL damage, only an amount that could be reasonably predicted.

Once this redundancy is exceeded the structure as a whole is going to behave in exactly the way the designers predicted and tried to design against.

It will fail, and with sufficient random damage, that failure will almost be symmetrical.
