lol whatever, I'm just answering the questions you put forth. I have answered them all, in detail, with facts to back me up, and the official response to them seems to be 'I don't believe it' without ever disproving a thing I say with evidence.
There are two plausible explanations I see, either that is a bit from above that has been sheared off by the lower part (it's on the right angle that we see the top half of the building fall at) or it is the section just below the blast zone and has been pushed out by the top half of the building. Unfortunately, I can't see inside the dust cloud.
then stop asking questions if you don't want answers.
in placement, immediately below the impact zone. It is unclear whether it is a section from the wall from below or above the impact zone, as it may be a section of the wall from the falling upper half that has been torn off.
Well it would depend on the specific construction of the building, but generally no, the building would not fall over. In this case, the upper part of the building crushed the rest of the building
ah but where are those images from? anybody could have manipulated them with photoshop, for a number of reasons, many of which are not malicious.
Because you have the brain capacity of a banana slug in a lead mine.
Like I said these are a few engineers, there are bound to be a few wackos in any profession. I tend to believe the many, many articles from the professionals who are much more professional than these people, and write peer-reviewed papers on the subject. There have been no conspiracy papers that have made it through the peer-review process to be published in a reputable scientific journal, whereas the peer-reviewed papers on my side of the argument are numerous.
You don't have the majority of physicists on your side, you don't have engineers, architects.
I have already explained this in detail, the floors offer less resistance, so they progression of the collapse is further along on the inside. Thus the wall sticks up over the collapse going on in the inside, and when it breaks off it falls out of the cloud.
I can't help it if you don't understand simple physics taught to 14 year olds. Seriously, physics is a non-negotiable science, until you start to get down to the atomic level or as big as the universe. You can't just not believe in it, this is not philosophy. You can't just make up your own physics, there are facts that must be observed, and things act according to the laws of physics.
It would appear to be some of the outer support columns that are still attached in a large chunk of wall, if we are seeing the same thing. Looks a lot like the section of wall still left standing on the left here:
Clearly I am doing a poor job explaining WTC7 - it is a much more complicated collapse than the two towers. let's try a different tact, letting someone else explain it for me. Pay special attention to the NIST video and the simulation images. http://www.youtube.com/watch?v ... re=player_embedded#at=67
Like I said it's commonly referred to as 'pancaking.' To think of what I'm describing as true pancaking (floors stack up on top of eachother) is a fallacy because the floors get pulverized by everything above it and add to the debris falling onto the next floor down. If you watch the videos, you can watch the debris be exploded out the side of the building slightly below where the support columns are still standing. This is because the support columns are the strongest thing in the building so they can withstand the debris a little longer and they are on the outside of the building so there is less material directly above them. Thus the pulverization of the floors outpaced the crushing of the support columns. It did not fall at free fall speed, it did take longer to destroy itself. Watch any video, look at any picture of the collapse of the two towers, and you can see rubble that is outpacing the fall of the tower.
Sections from the side falling past the building as it comes down - this is because the collapse of the building is slowed by hitting iteslf on the way down over and over:
It was an analogy to display the underlying physics in an easy to imagine scenario... I used people simply because in my experience most people have a more intuitive grasp of the physics of their own body than physical objects. I'm guessing this is because we (hopefully) move our body every day, and can feel the muscles moving to provide forces... now the rest of the system, specifically for the collapse of the lowers section is quite different, as I made a point to note. our joints are our weak spots in terms of sustaining a vertical force from above. In a building it's a different story, the weak sections are the floors first, followed by the structure. Now in terms of why we would be able to withstand a dog vs a human, that comes down to biomechanics. Our body is capable of producing an upwards force through the contraction of muscles. Put a weight bar on your back, your legs get tired faster because you are using muscles to push upwards. A building is incapable of producing an upwards force. Furthermore, it is not as flexible a system as our bodies, which would help dissipate and deflect some of the energy.
It is not a problem of whether the exact ratios of weight are right in the analogy - it is a matter of whether the weight above the lower object is enough to break the weakest link in the lower object.
essentially yes, that is what I'm saying. Of course the diagrams you drew are a much simpler version of the building structure, but I think that's about the best anyone can do illustrating with a keyboard Important to note that those rows are around the entire perimeter of the floors, with another set of supports in a column in the center of the building.
The support columns were not constructed the way many large buildings are. The columns were not concrete encased, which would have been a more effective method of fire prevention than the 2-hour-rated spray on fireproofing they used. If the columns had been concrete encased, I think there would have been a much less chance it came down, all other things being equal.
It's a picture of my cock
Have you ever tried to type the necessary variables and math equations on a computer? it's tedious, I try to avoid it as much as possible. Besides, I could fake that too if I was really determined to live a charade on this forum and this is taking me quite enough time already.
why? how the flying **** can you not understand that, I am trying to lay it out as simple as possible... ok, to use a very oversimplified analogy... imagine someone standing on your shoulders. Their foot slips off your shoulder. what happens? they fall. pause. at this point they are falling, you are not... yet. They are slightly tilted in the air because their foot slipped off and they have rotated ever so slightly. Now resume. they fall on top of you, and your knees buckle or you bend at the waist and you hit the ground too. Buildings do not have knees though, so the overwhelming weight will cause the weakest points of the building below them to collapse. In this case, the building is symmetrical, so the floors collapse in an effect commonly referred to as "pancaking" in these arguments.
Now the foot slipping off is not precisely the same sort of collapse, because it rotates from a different point, but the effect is still the same.
You think mechanical structures can't sag with enough pressure? lol ok, this is getting laughable now. The construction of this building leaves it particularly vulnerable to sagging, as it is not a concrete structure. It is like a giant erector set, and when the steel heats up enough and is supporting enough weight... bye bye
Get a longish steel rod of a certain width and you can bend it with your hands. If the force is great enough on any bar or floor, it can and will bend, causing sagging of the floors first and the visible kink when the structure lets go.
Your entire argument seems to be that I can't possibly be who I say I am and that you know so much better without ever having done any of the math or even attempting to consider my input. I was trying to make this as easy to undestand as possible for you, and then when you complain about that and I give you a more in depth post you just laugh it off. wtf
Look up the college if you doubt the quality of the teaching there.
So it's hard for pilots to hit the runway every time? just to be clear that is roughly the width of the buildings, and they didn't have to land on them, just run into it.
if there was a good way to prove it to you, I would. But I'm at home in Michigan this semester, makes it pretty hard to take a picture with the civil engineering building and a written card that says 'RiseAgainstMe!.' Could give you a pic in my GT gear... but lots of people could have GT gear and not go to school there, so that doesn't really prove anything.
Just because it was leaning doesn't mean it toppled. It did fall slightly out of its footprint, to the south. The first side to fall was the South, and then the North. You seem to be operating under the impression that the building fell in one piece, when it fell in sections, collapsing, not toppling. This is shown in the photos of the wreckage, as the north wall lays on top of the rest of the wreckage, as well as the videos. you can watch the East and West suites fall first, followed a few second later by the rest of the building. It looking like it is falling straight down is a trick of the most widely used camera angle.
looking at this image, wt7 doesn't seem to be falling so nice and symmetrical. There is a kink in the middle where the structure has sagged and was the first place to buckle. It is not falling straight down, but rather the top section is falling sideways through the rest of the building. The rest of the building had no choice but to follow.
An asymmetrical collapse did not change into a symmetrical one mid-fall. A slightly asymmetrical collapse caused a symmetrical one underneath it.
To solve this problem you have to think of the tower as two seperate objects once that random point in the middle that is holding everything else up buckles. The top object falls randomly, probably slightly sideways. It is no longer attached to the bottom object, but it is still in contact with it, as gravity is accelerating the object downwards. this extra force on the lower sections is enough to buckle the supports on the lower floors, causing the symmetrical collapse of the lower section in a chain reaction.
The steel broke after intense heat softened it and enormous amounts of weight it wasn't designed to hold were supported on it. Sorry I left a little bit out because I had already explained it, and I have been using very basic terms, because I know that a lot of the people I am talking to on forums and stuff are not engineers. If I start rambling on about Fstatic, no one will understand me or pay attention. Structural steel loses strength very quickly at a certain temperature, but it melts at a much higher temperature. this is because it is not an element, so it doesn't have a single melting point like say water does. It's an alloy, meaning there are several elements mixed up in there (different concentrations and treatments are used for different applications) - each with its own individual melting point. This causes the steel to have different phases as it heats up, and there is a rapid drop off in the strength of structural steel at a much lower temperature than the actual melting point. look up the yield curves on various types of steel if you don't believe me, they drop off very quickly.
The jet fuel burned up, yes, but by that time it had already set a lot of other things on fire - carpet, desks, walls, floors, ceilings.
metal is an extremely good conductor. this is why metal usually feels cold to the touch, that is the transfer of heat energy from your skin to the metal. That is it absorbs heat. Air is a bad conductor. The heat would have been absorbed by the metal easily, and stayed there for a long time. Air is a bad conductor.
I call them like I see them. I'm not going to say I respect them when I don't . Not everyone associated with this movement gets the crackpot label, it has to do with the thought process they lay out before me. If a person has achieved my label of crackpottidom, I believe them incapable of listening to my side of a debate, and thus unworthy of a debate. Hence why you got this entire response, and Racer X I don't pay attention to, should he ever choose to come back around here. Not all these talking videos I've seen have achieved that status - that last guy, Obeid or whatever I didn't think was too bad. I still disagree with his final conclusion though.
You don't KNOW anything. you think we aren't being told the truth.
A few engineers do not speak for us all. I would be quite surprised if they are anything near half the population of 'experts'.
I am an engineer, not a writer. Not my strength, but I do know what I'm talking about.
Building 7 was not a symmetrical collapse, but we weren't talking about that. It leaned to the side for hours before it collapsed. It was known that it would collapse long before it did. The lower sections of the two towers were symmetrical collapses, (weight falling on them) while the upper sections weren't, as the pieces that collapsed and bulged underneath them were asymmetrical (due to fire)
Of course a furnace loses some heat through dissipation. But stick your head in the thing and tell me it's not hot in there. That is literally the exact same idea. Fire inside a container. Jet fuel burns well past the temperature that is needed to weaken steel. The heat was transferred to the steel, and it broke it. And yes I'm trying to tell you that a 110 story highrise with fires on ten of those floors will not dissipate heat in an hours time. A small furnace for pottery can take hours and hours to cool, why doesn't the heat dissipate immediately into the floor?
Yes, I am calling them crackpots. This doesn't mean they don't have the qualifications, it just means they are crazy.
Oh I'm sorry, maybe I should clarify. I'm a civil engineer from the Georgia Institute of Technology. Very soon I will have every bit of the school time as these people, in a relevant field
It is my expert opinion that they are crackpots. got it?
The structure didn't begin an asymetrical collapse ffs. That's what I've been trying to explain to you. The collapse was a symmetrical one, the damage from the plane did not cause the collapse directly, the supports softened and buckled.
And the heat can't dissapate immediately you dolt, it doesn't work like that. It was trapped. Eventually it will yes, but there was also an intense heat source in the building that was creating more heat faster than the rest of the heat could dissipate. to dumb it down somewhat.
She was likely beaten on the ACT by a walnut. Metallurgical Engineer - who cares, she clearly lacks expertise in critical thinking skills.
She thinks that was an "office fire"? but a blast furnace is a different story? what does she think a fully fueled 747 crashing into a skyscraper creates? She dismisses it like it's a normal office fire, as if any office fire is normal.
The building falling straight: The building didn't collapse from the damage of the plane, she said that herself when she was talking about the melting steel. It fell because the steel structural supports were put under enough intense heat to cause them to lose structural strength and they eventually buckled under the weight of the floors above them. when the top floors fell The main supports are in the middle of the building which is why it fell symmetrically. on top of the bottom floors it set off a chain reaction and the building fell through itself. The spheres are consistent with this, as for all the metal to weaken that much, I'm guessing some of it had to be molten.
"Heat will not migrate towards itself" she seems to think that this a completely open system. The heat can't dissapate like it normally would, it's trapped inside a building with a raging fire. Seriously, this is some of the worst 'science' I have ever heard.
"Doesn't take an expert to see..." All it takes to believe her is a complete suspension of the laws of physics and common sense. She has my utter contempt as a human and as an engineer.
they had flight training and you can fly a plane with no flight training. Landing is the hard bit, and they didn't exactly have to worry about that.
Mythbusters proved that even never having flown a plane, the tower can talk you down safely. Pretty sure that having instruction before hand makes things even easier.
I've always wanted to get married since I was a little kid... Never like "oh my god I need to start looking for a wife in high school" or anything, even though it's starting to look more and more like that's what happened... There's just something comforting in that status for me, even if I'm an atheist (technically catholic). It's just home. I'm not one for big ceremonies and religious stuff though, so I don't know which type of wedding it would end up being...
I'm guessing the religious ceremony type is what's expected of me by my parents and would be by my current girlfriend's parents, seeing as they both sent us to Catholic school. I'd prefer to just shotgun the whole thing and just run away and turn up two weeks later and be like "hey we're married!" Guessing that's not gonna fly.
But to be honest there's no reason why someone has to get married, save for maybe tax reasons. It really shouldn't change how you feel about someone, but it can be comforting to many people. It's just an extra commitment to that bond, and if you don't feel the need to make that commitment, great.
