We just need to get people to understand the square cube law.
Please help me understand.
If we were to build an exact duplicate of the north tower at 1/10th scale of the exact same materials it would be 136 feet tall and 20 feet wide. So
being 1/10th as tall and long and wide it would weigh 1/1000th as much.
But the strength of a column is related to the cross sectional area which is two dimensional. So every column would have 1/100th the strength of
the real tower but it has 1/1000th the weight so the model would actually be TEN TIMES AS STRONG in relation to it's weight. So it could not possibly
collapse like the real tower due to its greater strength. So actually the design of the model would have to be changed to keep the strength to weight
ratio the same as the full size building in order to duplicate the physics. Perhaps the columns could be made of copper instead of steel. Or maybe
thinner steel. But that would change the weight in addition to the strength.
So getting the model's behavior to be the same as the real building's should have been if the plane could cause the collapse would take significant
effort. Of course all of the people who BELIEVE in the collapse would find some objections if the model will not do what they expect.
This is why my tiny model uses PAPER FOR SUPPORTS. So I use paper to make the supports as weak as possible relative to the weight they must support
under static conditions. But my model still arrests. Skyscrapers are not designed to be as weak as possible relative to their weight. So any
accurate model should not collapse. Curious how no engineering school discusses building one.
