Conspiracy v. fact 9/11

64. An aside...

Nuke,

I wrote this as an aside in my previous answer to your question about thermite. My posts are insufferably long as it is, so I stripped it out.

I was about to dump it, but thought that you are one of the few people that are still asking honest questions. (Good for you!) Perhaps you'd like to read it. It addresses the question "Where did all the energy come from to hurl all those columns so far?"

Here 'tis.
(This was going to be inserted right after "... I'd be shocked if the bolts would not fail if you just tilted a single upper column by 10° or so, just under its own weight, with no additional side load.&quot

The fact that they held together thru the fall (most landed in long, continuous, still-connected sheets) is, to me, nothing short of amazing.

(Aside:
BTW, this answers another "truther mystery": "Where did all the energy come from to 'hurl' those multi-ton column assemblies so far?" The answer is "The vast majority were not 'hurled', they tilted outward in sheets. For those that fell in sheets, it takes no work to displace them to the side, other than the tiny amount required to snap their lateral connections to the floor trusses."

The "by demo" explanation is: Imagine a perfectly vertical ladder with weights hung from every rung. If you tilt the ladder a tiny amount, it'll fall to the side, taking the weights with it. No additional work required.

The technical explanation is that Work = Force x Distance Displaced. But Force & Distance are vector (not scalar) quantities, so the proper equation is: W = F x D x cos(Ø), where Ø = angle between force vector & displacement vector at each instant. For a ladder (or the external columns), the force is always "up the vertical supports", and the instantaneous displacement is always "90° to the vertical supports". Since cos(90°) = 0, the work = 0.

Note: the above applies only to those columns that tilted outward in sheets, not the ones that were flung out individually or in groups, but not connected at their bottoms. But, if you look at the photos of GZ, you'll see that all the far-flung columns (e.g., that hit Winter Gardens) were part of sheets. The individual ones didn't travel nearly as far.
(End Aside.)
