There should have been at least a 3 to 5g deceleration by the upper section in a natural collapse, or ten times that observed
For all you with delusions of the realcddeal, the velocity is much slower than a free gravity falling object. So your lack of engineering skills and inability to resolve the difference between models and reality is your failure which is confirmed by reality based engineering instead of conspiracy based delusions.The Missing Jolt considers the first collision between floors so they are in place there chief. Nice try but no cigar.
To all you believers in a natural collapse
No deceleration and no velocity loss = an unnatural event
I hope that isn't too complex for you.
Keep trying to prop up your irreducible delusion. That was one projection by Ryan Mackey which is hard to forget.
You've said this about a hundred times, but repetition won't make it true.
Again, why won't you answer the questions put to you? It's not like they're unreasonable. You're the one selling a story here, you should expect some questions.
obviously, the building was blown up at the base, and it took off like a rocket ship.OK, I'm lost. Can someone tell me how you can have a deceleration greater than unity?

I have said repeatedly that I believe some unnatural mechanism was removing the strength of the columns in the Twin Towers and WTC 7 and causing their respective collapses.
Szamboti about Mackey -'...You only have what you claim to be a lack of sound as a means to argue against explosives. Nano-thermite is tailorable and can be formulated to minimize sound. The joints could be heat weakened and I told you that Dr. Astaneh mentioned melting at the ends of beams and columns. I also don't think it is out of the realm of possibility the core columns in the upper stories could be taken out in ways similar to what is done in the Verinage Technique.
I answered plenty of questions on this subject and if some of these guys don't get it maybe it is because they don't want to.
You should explain to those who don't understand that a static load is actually being decelerated at 1g and any load amplification would come from deceleration greater than that. You should help your friends here and answer that for them as it doesn't sound like some of them want to hear it from me.
Actually...Is deceleration defined as "A jerk going nowhere fast"?
Who mentioned flinging things around? Are you imagining things?
obviously, the building was blown up at the base, and it took off like a rocket ship.
All seriousness aside, one can figure the "decelleration" as a function of time:Is deceleration defined as "A jerk going nowhere fast"?
If a cat can kill a rat in a minute, how long would it be killing 60,000 rats? Ah, how long, indeed! My private opinion is that the rats would kill the cat.

If you hold a book at eye level and drop it smack on the floor, it accelerates downward at 1g until it collides with the floor, at which point it decelerates at a rate far greater than 1g for a correspondingly briefer time. That's the (controversial part of) Tony's missing jolt.OK, I'm lost. Can someone tell me how you can have a deceleration greater than unity?
Maybe Tony thinks the WTC should have shot up into the sky?OK, I'm lost. Can someone tell me how you can have a deceleration greater than unity?
Lewis Carroll once wrote a wonderful little essay on the folly of assuming linearity holds outside a model's region of linearity. Its conclusion:
I see that rwguinn has already given a similar answer to 3bodyproblem's question while I was writing this, but I'm going to post my answer anyway:
If you hold a book at eye level and drop it smack on the floor, it accelerates downward at 1g until it collides with the floor, at which point it decelerates at a rate far greater than 1g for a correspondingly briefer time. That's the (controversial part of) Tony's missing jolt.
If you drop the twelve upper floors of a WTC tower onto the floor below, then the upper section accelerates downward at a little less than 1g until it collides with the floor below, at which point that floor and its connections smash into pieces, cease to bear the loads they were capable of bearing in their undamaged state, heed the call of gravity, and the upper section continues its descent with only a small loss of downward velocity.
Tony disagrees, of course. He likes to calculate the size of the jolt as though the floor's failure has absolutely no effect on the total impulse it is able to deliver in opposition to the upper section's descent. He likes to imagine that the pieces of the smashed floor continue to exert significant upward force long after their connections to each other have been broken by the initial shock. On the other hand, Tony doesn't appreciate it when people call attention to that aspect of his argument.
Unfortunately, the experiment has already been performed. The rats killed the cat.
And there is your fundamental error--your irreducible delusion.You started out well but finished off with a bad turn.
The shock load is what is necessary to break and fail the lower structure and accelerate it. It occurs due to this is happening not after. After being broken and failed the floors and columns will not continue to exert a significant upward force. In order for the shock to be of sufficient magnitude there must be a significant amplification of the insufficient static load and this requires deceleration and velocity loss. If this did not happen it means the lower structure was broken before impact.
And there is your fundamental error--your irreducible delusion.
The Earth is acting on it to accelerate it. Once broken, it don't need no steenking jolt-gravity takes over and gets the assist.
