[QUOTE="Dutch_Mix"][QUOTE="xscrapzx"][QUOTE="Dutch_Mix"][QUOTE="xscrapzx"]Um all you have to do is look at the trucks that were pulling away with steel beams, thats taking away evidence that could of been investigated to see what the hell melted the steel beams. Instead it was taken away and sent off to be recycled. Don't see anything wrong with that?

Oh, so that's where all the evidence went, huh? :roll:
Anyway, the jet fuel from the planes didn't have to melt through the beams in order to bring down the towers. The fires simply had to be hot enough so that the structural integrity of the beams would be compromised.
Which is true but how many floors again where burning and for how long? Also how many floors did those floors take out? Think about it. Just think of the 40 something beams in the middle of the building collasping on itself like a preztel and on top of the 80+ floors that crumbled like bread.
I'm not really sure what type of analogy you're using so I'm going to use one of my own...
The towers fell similar to how an accordian is compressed because you can see as the building collapses on itself, the oxygen is blowing out the windows on each floor. Again, this is because the beams could not support the weight of the floors above the point of impact.
Gosh, I think I've already made this point in similar 9/11 conspiracy threads.
Thats what I'm trying to say... Do you really believe that 10+ stories that were burning pretty hott, no doubt on that part. Took out 85+ stories below it with ease, with absolutely no resistence of any kind from the floors that is was collapsing on? Not only actually imagining the beams in the middle folding like an according, come on think about that, and you do you really believe if you dropped a piece of concrete from a thousand feet that it would break into powder?
Sorry to get into the middle of both of your discussion, but structural energy management is part of my day to day. With that said perhaps I can interject?
The best way I can discribe the situation would be like this;
Build a 25 level model, (roughly 1/4 in terms of floors) with four stand alone supports per level placed in each corner with a piece of tempered glass as the "floor" for each level. Lets make the glass an 1/8 of an inch thick and 8" squared and the supports made of hollow stainless steel tubes (EDIT: Lets make the tubes aluminum, based on the model I am playing with we may as well save the weight), with the base of the unit being a flat piece of cement.
Now place a standard 4.4 lbs red clay brick (4" x 2 2/3" x 8") on every level, except 7, 14, and 20 where you would place six hollow tubes rather then the standard four and no brick.
You will find that the tower should stand without issue, no cracks in the glass (Assuming you are using the correct glass). You could sit it like this for days and unless someone messed with it, it should just stand there.
Now tie a string to the four support beams on level 22, and yank em out.
You now have the energy of 13.2 pounds of brick slamming down on the brick on level 22. The weight or energy was being spread over four supports on each floor over the glass surface, now 13.2 pounds (plus the minimal weight of the supports and the glass) or force are being exerted on the highest point of level 22 (the top of the brick)
There should be a brief (less then a second) stop on level 20 which is a support floor but then the pile of bricks will smash right down the middle of the tower and the whole thing will come crashing down.
Because you are changing the way the energy of the building is being managed, and not only asking it to hold up to the weight it was designed for, but the applied force from above focused at one point.
To really summerize, your wooden shelf in the garage can hold your sledge hammer on the top shelf with no issue, but if I swing that hammer even lightly the applied force becomes much greater and chances are will smash right through the top shelf.
EDIT 1: Changed supports to aluminum
