Touché, but it seems like such an obvious sabotage, I wonder how Trump rationalized it.

I don't know if any of the engineers or architects read this thread but I'd be curious on their takes on building 7's collapse. I'm a mechanical engineer with 2 courses in structural (and plenty in mechanics of materials), even though it's not what I currently do. Yes, it is absolutely reasonable: http://www.steelconstruction.info/Fire_damage_assessment_of_hot_rolled_structural_steelwork The WTC's structure was made of the low carbon ductile steel. These alloys are super sensitive to high temperatures, and by simply looking and by looking at a phase diagram of steel: https://www.google.com/search?q=steel phase diagram&espv=2&rlz=1C1CHBD_enCA703CA705&biw=1680&bih=920&source=lnms&tbm=isch&sa=X&sqi=2&ved=0ahUKEwidmOvIy6HPAhUUR2MKHcRvAuAQ_AUIBigB#imgrc=tAW4mT3SrMuchM: You know that the idiots spewing crap about how steel melts at 1500C have no idea what they are talking about. Any mechanical or civil engineer that thinks it's not extremely plausible that the building could collapse under such conditions is promoting unfounded conspiracy theories and should be removed from his position if it's a position of sound scientific judgement. edit: Also, the effect of weakening of the steel is doubled, as one, it has a weaker yield strength, but its value in young's modulus also decrease, so the inherent instability of the building is exemplified, and thus certain members will be bearing more weight, while being weaker. There's other factors such as thermal expansion resulting in lengthening of certain beams, which also messes with the geometry to create an uneven load distribution, and so forth. | ||

I'm not talking about the twin towers at all. I'm talking about WTC-7. Sounds like you guys are like me and just wrote it off as Alex Jones stuff without looking much deeper. If anyone knows anything about WTC-7 I'd be interested in hearing from them. | ||

TRUMP OPPOSES PRESIDENT OBAMA’S PLAN TO SURRENDER AMERICAN INTERNET CONTROL TO FOREIGN POWERS "Donald J. Trump is committed to preserving Internet freedom for the American people and citizens all over the world. The U.S. should not turn control of the Internet over to the United Nations and the international community. President Obama intends to do so on his own authority – just 10 days from now, on October 1st, unless Congress acts quickly to stop him. The Republicans in Congress are admirably leading a fight to save the Internet this week, and need all the help the American people can give them to be successful. Hillary Clinton’s Democrats are refusing to protect the American people by not protecting the Internet. The U.S. created, developed and expanded the Internet across the globe. U.S. oversight has kept the Internet free and open without government censorship – a fundamental American value rooted in our Constitution’s Free Speech clause. Internet freedom is now at risk with the President’s intent to cede control to international interests, including countries like China and Russia, which have a long track record of trying to impose online censorship. Congress needs to act, or Internet freedom will be lost for good, since there will be no way to make it great again once it is lost." - Stephen Miller, National Policy Director https://www.donaldjtrump.com/press-releases/donald-j.-trump-opposes-president-obama-plan-to-surrender-american-internet Is Cruz now Donald's tech advisor? ICANN has nothing to do with censorship or muh freedom | ||

Hey GH. We've done this dance several times. You are a guy of above average intelligence and I presume you're pretty good at whatever your field of study or work is. However, your field does not seem to be biology, medicine, engineering, finance/ accounting, law or economics. So maybe at a certain point it would be prudent to defer to posters who have more knowledge and experience on the subjects instead of peddling stuff like this. | ||

I think I'm going to call you out on this one and see what happens. GH was bringing up a very reasonable point against you two pages ago. Notice how you completely ignored it and just came back now that the truther talk is happening so that you get to look reasonable again even though you have discontinued the other conversation? | ||

Most things are designed to withstand any one bad thing happening to it at once, so a fire for example, sure. It's tough to anticipate a large combination of things at once, and usually this results in the negative effects amplifying themselves many times. I remember watching a documentary years and years back that said something about bad fireproofing standards on the steel, then you have a massive shock to the foundation when other things are collapsing, that's the building going through an earthquake. You have debris hitting the building from the other stuff happening. Combine that with the fire going on for hours on end. And now when quickly skimming wikipedia, I see some stuff about a sprinkler system needing manual initiation, low water pressure to deal with the flow rate of water needed, and who knows, maybe some minor construction faults as well. Point is, a reasonable number of buildings would have fallen in these circumstances... Would all? Unlikely, but it's completely feasible for it to happen, say the average skyscraper would have a 30-50% chance of falling in this situation. When you girlfriend told you she finished eating the food you made she didn't like and there was a 50% chance she ate it and a 50% chance she threw it out, is your reaction to go check the garbage can? It's a completely realistic thing to happen, and I don't know why people keep trying to hang onto these things so tight. edit: We're good at removing all the SPoF in a project, but there's always the chance of a complex failure due to things that our imagination didn't consider. There might be 3 things that have a 1 in 10,000 event that breaks 1 of 3 things, if you assume they are independent events, then you're doing pretty good with a 1 in trillion chance of failure, but maybe you miss how there might be a causation between these things in certain circumstances, and voila... Instead of there being a 1 in 10,000 chance of a fire every day, 1 in 10,000 chance of the sprinkler breaking, and 1 in 10,000 chance of some debris damaging a few columns, they might have perfect causation, and now you're at a failure every 10,000 days instead of 1 every 1 trillion. Just a very simple example, but just to show the importance of doing some risk analysis and that it isn't so simple on the surface. | ||
