Apparently we can't even be told the tons of steel on the 80th, 81st and 82nd stories of the south tower where the plane hit.

What does your second sentence mean?

The fuselage of the aircraft hit the south tower at the 81st floor. But since it was 17 feet in diameter and the floors were 12 feet apart at least two levels were seriously impacted. That means there had to be enough steel there to support the weight of another 29 stories. The plane impacted at 550 mph but the building only deflected 15 inches and oscillated for four minutes. Doesn't sound too feeble to me. So how did that much steel weaken in less than one hour and yet in NINE YEARS we can't be told the tons of steel on each level.
So if people BELIEVE in the 9/11 Religion then their FAITH sustains them and precludes the need to ask obvious questions. LOL

Dear LOL,
There was enough steel there to support the weight of 29 stories until it was weakened by fire. How did that much steel weaken? Because that much steel was exposed to fire after the impact had removed the fireproofing. As to tons of steel on each level, that should be readly estimated from the building plans. Previously, you were complaining about not being provided the weight of each floor and it was explained to you that the amount of interior drywall partitions and office furnishings were unknown and, hence, the weights of individual floors were unknown.
I hope your faith continues to sustain you.

The time to heat some quantity of steel to a given temperature would depend on the heat produced by the fires, the Cp of the steel, and transfer coefficients. Heat could be transferred convectively and radiatively and would be different for insulated steel and uninsuated steel. You also seem to be assuming that all steel must be heated and that the fires are homogenously distributed.
These unknowns and the unknown amount of fuel available to the fires will make this a complicated calculation that will require a good deal of estimation which, in itself, may actually dictate the answer you get.

You are saying that if all other factors remain constant that raising the temperature of 100 tons of steel 10 degrees C would take the same time as raising that of 10 tons of steel or 500 tons of steel?

Ask a cook if it takes the same amount of time to cook a turkey regardless of the size of the turkey.

That is not what I said at all. The fires may not have been homogenous and they may not have heated all of the steel; only enough to cause failure.There will have to be a lot of assumptions on your part and the assumptions that you must make may determine the outcome.

You are operating in a logical circle of ignorance. If we just BELIEVE enough steel could get hot enough to cause total failures in 56 minutes and 102 minutes then we don't need to know how much steel was there to be weakened or how it could have conducted heat away from the fire. YEAH RIGHT!
Why weren't the experts demanding to know the distributions of steel and concrete within weeks of 9/11? The trouble is if they say that information is important and demand it now then they will look pretty stupid for not having done so 9 years ago.

You aren't making any assumptions yet, other than your implication that all steel was heated to the same temperature by homogenous fires. To do any sort of calculations, you will have to make some assumptions regarding the amount of fuel available and the distributions of the fuel on the levels in question. If you assume that there was enough fuel to burn for two hours and that all steel was heated to 1000 F, you may be able to do some calculations but what would they prove?

How can there be any such thing as a homogeneous fire except under deliberate artificially created conditions?
Column sections were 36 feet long. The ends were connected to other columns and beams. Heat would be conducted away from the fire under almost any circumstances. But the amount of TIME required to heat the steel to the point of weakening would be affected by the amount of steel no matter what.
So why isn't such an obvious fact mentioned and explained in NINE YEARS?
Someone did a calculation long ago with various simplifying assumptions. But the conclusion is not gratifying to believers in a fire induced collapse.
One would think it would be possible to compute the amount of energy required if the quantity of steel were known and then calculate the fuel requirements. If those fuel requirements turned out to be obviously ridiculous then....
But most people seem to be operating on the BELIEVE THE FORE COULD SO IT and let it go at that.

How will you deal with the distribution of fuel within the fire? As the fires burned from the impacts to the collapses, there was enough fuel present. If there was enough fuel present for a continuous burn, how would you estimate temperatures of individual components?

This entire event is already ridiculous based on existing data. We just have lots of people eager to believe obvious nonsense as long as someone will tell them what they want to hear.
