Well, 10,001 hits on 10/4/11. It took almost 4 years. Views started leveling off around June of 2009. So when I America going to do physics? Probably can't handle the psychological shock.

Just wondering, but have you noticed that this model is significantly stronger than the tower construction? The towers' main strength lay in the core column, and the outer panels were only held on by the trusses extending from the core. Therefor, a possibly more accurate portrayal would be if you used popsicle sticks or something (though those are probably too strong as well).

There is simply a fundamental flaw in your model. It does not accurately represent the physics.

@Daniel092004 The purpose of that model was to show that the response of the structure due to the impact changed with the mass and the distribution of mass in the structure. Therefore that information had to be necessary to analyze the effect of the airliner impact on the towers.

So why hasn't everyone been demanding the steel and concrete data on the towers?

It's only been TEN YEARS!

[psikeyhackr]

Well, it's that day. TEN YEARS of Bad Physics!

The Physics Profession has not demanded accurate data on the distributions of steel and concrete down the towers. Who cares about Potential Energy and the Conservation of Momentum?

I guess it is time to burn Isaac Newton in effigy.

your impact object did not penetrate your model. I would like to see what would happen to your model if the object did take out half of a level...

[psikeyhackr]

@teampenit My impact mass was 8 to 25% of the weight of my model.

The airliner was less then 1/2 of 1/10th of 1% of the mass of the towers. One floor slab was more than triple the weight of the plane.

Dr Sunder of the NIST said the north tower came down in 11 seconds. Argue with him. It is in a podcast on PBS.

I am approaching the point where I decide to delete everything you post because it is nothing but idiotic drivel.

[ItsAllCoolio]

Ye I agree. I'd love that info. But still this video is irrelevant to the collapse. If you notice in the calcs I mentioned I had to assume a weight for each floor based on an assumed concrete slab thickness. I seen your other vids and they are the most thought out models I have seen on youtube (thats not hard) but its difficult to draw conclusions from them. I think it would not be a stretch to assume the weight of each floor would be the same as any differences would be negligible

[teampenit]

the evidence to me that pancaking happened comes from the videos of the collapse, the portion above the point of impact retained its shape and it's orientation as dust and debris came out from the pancaking levels below the point of impact....and it is that downward pancaking that pulverized the majority of the buildings.

[teampenit]

the plane took out not just one level but parts of several levels. when that first level collapsed, the floor directly below had to withstand the impact of not just the weight of the floor directly above but the weight of ALL the floors above that point. The amount of energy transferred had to be huge. I am sure there are people out there that could do a calculation based on guesstimates...I can accept the idea that pancaking downward, once it started was unstoppable

[teampenit]

screaming "TONS of STEEL and TONS of CONCRETE in SEVEN YEARS" over and over does not make your argument any more valid, you don't win a debate based on how many times you say the same thing over and over...

your model did not get penetrated, it did not catch on fire, it's useless.

[psikeyhackr]

@Insolent85 Doesn't that mean the CORE TEMPERATURE of the steel has to rise to that level? How much time does that take? How could it happen in LESS THAN ONE HOUR for the south tower when there had to be enough steel there to support another TWENTY NINE STORIES?
