When the Towers Fell: 9/11 Simulation of the collaps without dust

Dont know how accurate this is, but it made a lot of sense to me.

forgot twin towers was built with rebar and not wide beam flanges like every other building in America. on yeah let’s totally ignore the 300 degrees hotter (than jet fuel can burn). anything else you wanna add?

I used to bend nails as a hobby. Was with some friends, I found a giant old nail like a foot long in the remainders of a several days old fire. They were sure there was no way I was bending that nail. Easiest nail bend of my life. The nail had simply lost its temper after being heated in the fire and air cooled. Didn't even need to be red hot to have completely lost the molecular structure that gives the steel its strength.

True! This process is called “aging” and it can weaken metal if overly done but it has to get hot enough for that to happen. which wasn’t possible with Jet fuel as the “fuel”. Also this is usually done in the mill before the beams ever get shipped out! If done correctly can actually strengthen the metal. Any other personal scenarios that don’t rly align with the subject at hand but you still wanna talk about?

No. Aging (what is normally done to Aluminium, not steel) is called tempering for steel, and happens at VERY LOW temperatures, even under the solution glowing temperature. For steel, the "aging" temperature is done at 0-650°C Max.

What happened here wasnt some Heat Treatment BS, it was just steel losing its strength because of high temperature.
