Chain of Custody

Yes I do realize that, but welding would not have produced microspheres to accumulate to 6% of the total of the WTC powder.

So how much would it account for? If you don't know how can you make the above statement?

 

[sheeplesnshills]

Really? are you saying that steel is NOT an alloy of iron with added carbon to make it flex?

Its added to increase its tensile strength not to increase its flexibility (although for some applications that is a useful characteristic.)

Everyone here knows that the TT were known to flex in high winds right? That's why the STEEL CORE COLUMNS thinned as you got closer to the top.

Right. However, the reason for the tapered steel columns is because of strength. Not because of flexibility.

If they had put the same size columns at the top, as the bottom, it may not have of worked. They columns would have had to be HUGE w/r/t thickness to be able to support the added load on them. By making them taper, you've reduced the load on the lower columns, thus reducing the size needed for the lower columns. It's all about weight.

I have spoken with people who worked in the towers whom have said you could feel them sway in high winds.

That is true of just about any large skyscraper. Sears Tower, ESB, etc. Less though with the ESB.

Jones took samples from known CDs. There were no red/gray chips or iron rich formerly molten microspheres found.

Were any of those CD's of a steel framed high rises? any of them on the scale of even WTC7

 

[sheeplesnshills]

So I have proven through citation that carbon added to iron makes steel flexible.

Do you really believe that? It can make it flexible, but that wholly depends on the heat treatment of the alloy. Its easy to make steel so brittle it will shatter like glass if you hit it hard enough.

Well brother you see it's the carbon amount that make er flex-y-bal.

Maybe in your world, Me, I have to stick to reality.

Nice knowing you. Bye, Bye.

Nope, they got thinner to reduce their weight. The columns were the same exterior dimensions all the way up the tower but needed to support much more load at the bottom than at the top so their walls were thinned down from about 2" thick at the bottom to 0.25" IIRC at the top.
This saves steel (and hence money) and means the lower columns had less weight to support.

"So how could steel possably NOT be flexible if 200,000 tons would flex in high winds.??

No one said that steel was not flexible (everything is to some extent) just that carbon is not added just to make it so.......which was your claim.

The kid said he took welding in High School. Isn't that good enough?


(By "took" I think he means "will take" when he gets there)

Taking shop classes in high school qualifies you as a structural engineer. Who knew?

I sometimes wish I had that power.

I think this guy is a welder, or at least was a welder in the Navy.

From the torch discussion, I'm doubting it.

 

[Oystein]

From the steel discussion, I doubt it even more

 

[NoahFence]

From any discussion I doubt it as well.
