Ni blizu tačnog (i logičnog).... Naime, da se zgrada ljulja 12m niko u zgradi ne bi ostao na nogama, niti bi zgrada ostala u jednom komadu.... evo ga info...
Does the Empire State Building move or sway?
The Empire State Building does not sway, it gives. With a wind of 110 miles an hour, the Building gives 1.48 inches. Movement off center is never greater than one quarter inch, thus measurable movement is only one half inch, one quarter inch on either side.
A što se tiče slobodnog pada WTC1 i WTC2 evo ga izvod iz dokumenta koji sve analizira u detalj... jer nije uporedivo 2kPa lateralnog pritiska od vetra za koji je projektovan, sa udarom fokusiranim na relativno malu površinu koji razara noseće stubove. Zaključak:
An analysis of the energetics of the WTC collapse events has shown that the kinetic energy of the aircraft collisions and the subsequent gravitational energy released by the descending blocks of floors were quite sufficient to destroy the twin towers in the manner observed. The use of explosive devices in either of the two towers is not necessary to explain the collapse events and is considered to be highly unlikely.
The times calculated for the collapse of WTC 1 and WTC 2 show good agreement with the observed collapse times verifying the basic assumptions of the momentum transfer model used in the calculations.
The calculated times represent the minimum theoretical times of building collapse. If shorter times are to be physically achieved they must involve an unknown additional source of energy acting in a downward direction. Such a source of energy does not appear to have been involved in the collapse of the twin towers.
The kinetic energy of the collapse events was sufficient to crush the WTC floor concrete in both towers to particles 100 micrometers in diameter, or smaller, which is consistent with the observed WTC debris particle size distribution.
From a consideration of the strength of the WTC columns, and the effective area of support they provided, it is demonstrated that the conditions necessary for the initial floor collapse were initiated by the aircraft impacts and made irrevocable by the subsequent eccentric loading of the core columns. The fires that were initiated by the jet fuel spilled within the towers certainly weakened steel in localized areas in the impact zones. However, it is suggested that the total collapse of both towers would have occurred even without the jet fuel fires.
Veoma je uporediv pritisak vetra na velikoj povrsini jer samo taj jednoznacni i ravnomerni pritisak omogucava simetricno rusenje zgrade.
U slucaju udara na nosece stubove , nikakva simetrija posebno u rusenju ne bi bila ni moguca, jer bi prvo nekontrolisano pao deo iznad udara, a tek posle ostalo.
Sto se brzine pada tice, bezina urusavanja zgrade koja se rusi zbog strukturallnih problema bi MORALA biti u najmanju ruku duplo a verovatno i trostruko manja od brzine slobodnog pada, A NIJE.
i naravno, OPET ne bi mogla biti simetricna ni na jedan nacin, jer je po TVOJIM recima doslo do strahovitog udara u jendoj tacki, kojom se po toj definiciji udara razara svaka simetrija, pa i u rusenju.
I ne moras da mi postavljas odgovore nekih komisija ili istrage.
Oni da vrede, na bilo koji nacin, ne bi bili toliko osporavani.
PS: Ako se ne varam zgrade Trgovinskog centra su napravljene kao cetiri nebodera od po 25 spratova koji su spojeni jedan na drugi(figurativno receno).
Zar ne bi udar ogromne snage imao ogroman uticaj na konstrukciju na mestu udara i iznad njega..........Zasto je imao uticaja na konstrukciju ISPOD udara?
Taj i toliki udar moze da se poredi sa odsecanjem(opet figurativno)......Zasto je onda uticao na donji deo konstrukcije(ovo je takodje povezano sa urusavanjem i njegovom brzinom)?
Gde ti na snimku rusenja zgrade vidis da se konstrukcija u bilo kojoj regiji zgrade "opirala" rusenju?
A ako je kompletna konstrukcija popustila, kako su popustile odjednom u celoj zgradi?
