6. Why would it slow if the falling mass was getting heavier every second?

KE=1/2 (mass X velocity squared). That means the energy applied to demolishing the next floor down grew every second.

Secondly, we know the structure was twisting when the collapse started based on how the spire fell and how the side walls were pulled in. So there were lateral forces on the vertical columns that would have ensured that they did not remain upright.

Here is the floor design:

The floors of the Twin Towers completed the structural system whose main elements were the core structures and the perimeter walls. The floor diaphragms were annular structures that spanned the distance between the core structures and the perimeter walls, providing large expanses of uninterrupted floor space. The cores had their own flooring systems, which were structurally independent of the surrounding floor diaphragms.

The floor diaphragms consisted of lightweight concrete slabs poured onto corrugated steel pans, which were supported by trusses. Primary double trusses were interwoven with transverse secondary trusses -- a fact ignored by the truss failure theory. The primary trusses were 900 mm deep, and spaced on 2.04 m centers

What a paranoia driven cognitive dissonance looks like e.g. David Chandler William Seger Nov 2015 #1

Chandler's correct! You are not! wildbilln864 Nov 2015 #2

The floor pans did not get more robust lower in the structure. hack89 Nov 2015 #3

show me the specs that prove your claim or else you... wildbilln864 Nov 2015 #4

Why would it slow if the falling mass was getting heavier every second? hack89 Nov 2015 #6

much of that "falling mass" wildbilln864 Nov 2015 #7

So it didn't collapse in its own footprint? hack89 Nov 2015 #8

7 did yes... wildbilln864 Nov 2015 #9

Since the collapse left a towering pile of debris that filled a massive hole in the ground hack89 Nov 2015 #10

you'd be wrong... wildbilln864 Nov 2015 #11

So you are denying there was a huge pile of debris that fill a huge hole in the ground? hack89 Nov 2015 #12

so now you are saying... wildbilln864 Nov 2015 #13

Pretty much. How else would heavy objects fall except straight down? hack89 Nov 2015 #15

so how did wildbilln864 Nov 2015 #21

Wasn't the basement mainly open space? hack89 Nov 2015 #23

Relatively little debris was going over the side William Seger Nov 2015 #16

well that's obvious bullshit! wildbilln864 Nov 2015 #22

A lot of dust and the external walls hack89 Nov 2015 #24

RELATIVELY little debris was going over the side William Seger Nov 2015 #25

We've been through all this before William Seger Nov 2015 #5

you are embarrasing the board not I. wildbilln864 Nov 2015 #14

"And Chandler shows how he comes to his conclusions which you cannot do." William Seger Nov 2015 #17

did you do the wildbilln864 Nov 2015 #18

No need to hunt for math errors William Seger Nov 2015 #19

so you can't. ok. n/t wildbilln864 Nov 2015 #20

so you won't. ok. n/t William Seger Nov 2015 #26

but I did William... wildbilln864 Nov 2015 #27

are you asserting there was... wildbilln864 Nov 2015 #28

No, I'm saying there was no "uniform" resistance to produce "constant" acceleration William Seger Nov 2015 #29

akin to that ridiculous wildbilln864 Nov 2015 #30

You're ignoring gravity William Seger Nov 2015 #31
