Prove me wrong Kyle.
PS: If he does solve the challenge I will apologize to him on this issue.
Well, I'll make an assumption that you agree that WTC 7 underwent for some period of time collapse equal to or near free fall... I saw it in one video fall beyond that magic 105' but that aside, I further assume you would agree that there is little or no deformation to the roof line fascia or the sides seen in the various videos or any portion seen except the roof proper where the penthouse lived prior to but maybe not during this Free Fall event.
We know or I think we agree that in order to Free Fall or nearly so there could not have been any structure resisting or better said.. no significant structure resisting the collapse for the duration of that portion.
That means to me that the failure of the vertical columns had to proceed the symmetrical collapse we see.
I deduce that the exterior fascia was held up by the exterior columns since that is the design criteria as I see it. IF the vertical support columns fail the fascia fails.
Assume for one scenario that all the inner core columns fail as per some logic... nothing there but the final bit that fails to enable the penthouse to fail but the exterior vertical columns do exist cuz we see them holding up the exterior fascia. Then the building all nice and symmetrical like collapses with at least 105' of which is at near free fall acceleration.
Now... what dynamic allowed the exterior to stand then drop at free fall? It seems to me a defect at least 105' below the top gave out equally around the building. Every column gave out at the same time all around the building at the same level so the symmetrical free fall could occur. I say the same floor but some could have been lower but not likely cuz I see a video of the corner section still falling below that 105' level and still all connected and looking much like it did during the entire fall.
That scenario agrees that the central core got all weak and somehow disconnected from the exterior and bent over and broke or what ever it did but it was of no consequence in resisting anything otherwise we'd have seen that. If any part resisted then that part would have sort of broke apart from the bit that didn't have Resistance cuz it couldn't free fall. I saw nothing like that happen.. the building exterior at least from all angles stayed intact as a unit even until it got to a level above the street and then tipped in to the back or front depending on the view I'm seeing.
What math would one need to opine on that scenario.. I think it is quite obvious from the videos.
The only question regarding the scenario above is what dynamic could have caused the exterior to give out at the same time at the same level so the exterior could free fall for the distance it did..
There are other scenarios but this one, at least don't need any math, I don't think. I stipulate that the core went poof and did so in a manner that provided no resistive force.
