Yeah, so what? Like I said, it was a shitload of steel and concrete, all longing to be rejoined with its mother, the Earth, but prevented from doing it by Science and Engineering. Precise numbers are far from necessary to figure that one out.
And where did that guy get that “all was dust” factoid, Judy Wood? Have you seen the photos of vast quantities of concrete rubble removed from the scene? Of course you have. You have been studying this for YEARS, so connect the dots. Big chunks are not dust.
I actually almost added a “You’re welcome” for the first wiseass who picked up on that AND had the lack of shame needed to admit it. I’m a straight man and happy to feed lines to you jokers.
You want distribution of mass? 100% of the mass of the building was distributed throughout the building.
Let propose a small experiment to show you why knowing the exact mass above the collapse doesn’t matter. It doesn’t matter if it was a shitload or a metric fuck ton.
My local Home Depot sells premixed concrete in 60 lb bags. They sell Portland cement in 94 lb bags.
I am not a hugely strong guy but I can put either of these bags on my shoulder and carry it. Give me a bit of assistance getting them there and I can carry a 60 on one shoulder and a 94 on the other, or 2 60s or 2 94s.
For the sake of this experiment we will assume you are at least as strong as I am
So we will take you to the Home Depot have you stand in one spot and raise two bags oh let’s say ten feet above you shoulders. We will then let them fall onto your shoulders.
Do you thing you will remain standing?
Do you think it would make any difference if they were each 60, each 94, or one of each?
Do you think the doctor looking at you shattered bones will claim nano thermite was used to weaken your shattered collarbone?
Lightweight concrete, such as that used for the floor slabs of the towers, is only about 1500 kg/m^3.
Almost all of the concrete used in the towers was in the floor slabs, and each floor slab was basically the same weight.
So that’s a pretty good estimate of the weight and distribution of the concrete in the towers. Now what are you going to do with that info? How is it relevant?
The problem is that the floor slabs do not account for that 425,000 cubic yards number. If the number is wrong than why is it wrong and why has it turned up so much? In fact I have never seen an official source say it is wrong. And that does not explain why the NIST does not even supply us with a total for the concrete.
:::sigh:::
Take your calculated cubic yard measure per floor multiply by 116.
Subtract that number from 425,000
Take that result and subtract 142.4 cubic yards.
You may now safely assume your final number is what was used in the foundation.
As I have said before this really isn’t rocket surgery.
Now that you know where all the concrete went, so what?
They must be talking about all the concrete used in the foundations - that would be a lot. By my quick figures, there should be something over 60,000 cubic yards of concrete within each tower, used for the floor slabs.
Now, what are you going to do with that?
ETA: I don’t know where the 425,000 number came from, but maybe it’s talking about the concrete used in all the buildings, including WTC1, 2, 3, 4, 5, 6, and 7?
Where are your calculations to show that any I made some mistake? All you can do is imply that I am wrong about something.
Calculations I did with 5 inch floor slabs and ignoring holes for elevator shafts still came up with 1/3rd as much as that 425,000 cubic yards. And no one ever said that the basement floors used the standard truss construction or lightweight. Why use lightweight concrete in the basement?
So if you want to imply I am wrong about something then show us YOUR CALCULATIONS. I did not make up that 425,000 cubic yards number.
(slab thickness in inches / 12) * length of floor in feet * width of floor in feet * number of floors / cubic feet in cubic yard = cubic yards per building
(4.333÷12)×206×206×116÷27 = 65,831.86 cubic yards per building
131,663.7 cubic yards for both buildings. So that is a bit short of 425,000 cubic yards.
So do you have better calculations which indicate something significant?
You can ASSUME whatever you want. Assumptions are quite likely not safe. It means trusting someone. There is no trust from me on this.
I am not interested in assuming anything. Since the NIST says nothing about 425,000 cubic yards of concrete than someone is spewing nonsense even if tacitly.
All of your claims about the concrete ar without foundation, (pun intended), and have no bearing on how and why the buildings fell. Your insistence that someone needs to hold your hand and explain irrelevant factoids has nothing to do with how and why the towers fell, and everything to do with you simply wanting to pretend that your are looking for “Truth” when you are simply quibbling over your own lack of understanding.
They did. Please provide your competing hypothesis and evidence for it. Stop this dancing around and “Just asking questions” and tell us what you think happened and why. You keep asking for these things, and we keep on telling you that it’s not only irrelevant but also an impossible standard of evidence, but somehow it just doesn’t seem to phase you at all.
I don’t need any calculations to show your errors
In this post you said you calculated a 5" floor thickness. In your very next post you used 4.33". Do I need to mention that these numbers aren’t equal?
Once again you are confusing things (probably on purpose) we are discussing volume not mass or type of construction.
A cubic yard of lightweight concrete takes up the same space as a cubic yard of regular concrete or for that matter a cubic yard of bullshit, a substance you appear to be familiar with.
My calculations are that the total volume less what was used on individual floors less the 142.9 cubic yards equals what was used in the foundation. A pair of 110 story buildings will take a whopping big foundation.
Don’t believe me? No problem. Go get a copy of the blueprints for the building and calculate the volume of concrete required for the foundation. At the same time you can find out how thick the floors are, since you seem to be a bit hazy on that subject.
Oh don’t forget to include sidewalks outside. They were also concrete.
I’m still waiting to see if my calculations were correct. Can you send this to your team of engineers, psikey, and have them verify that 6/116 really does equal .0517… ?
This could be the break the McCain campaign has been waiting for!
