Have you ever wondered how the World Trade Center fell as it appeared? It is believed that it fell mainly due to the heat of the burning fuel and inadequate construction materials and design. As it is shown about how it all started, but plots about how it slowly fell apart, how it happened. There are many other opinions on this issue, but I believe this is how it happened. Many reasons we can't explain but think it's the truth. There are many different materials available today that look like what we all think they should be. “Were the tops of the trusses embedded in the concrete slab, so even if a truss was heated to the breaking point, even if it was dripping with molten steel, the concrete slab would still hold the truss and she couldn't do it. fall as shown in the animation. (Collapse: An Engineer's Perspective) “Buckling columns requires energy, and deformation of steel beyond the elastic range dissipates energy. But free fall – or gravitational acceleration – converts gravitational potential energy into kinetic energy, leaving nothing left to do the mechanical work needed to crush a steel frame supporting 40 stories. (The Pacifica Radio) The material they used was flammable. The metal used for construction appeared to be steel, but it was actually a cheaper alternative. The designers wanted to save money and so used a cheaper version of a similar type of steel material, which caused the building to easily collapse. That being said, as one pillar fell, the rest fell with it like a domino destroying whatever had caused the top of the building to begin with. Bombs are the best way to destroy tall buildings these days and are used daily. bases for demolishing buildings from ...... middle of paper ....... With even bombs aboard the plane, the impact would increase the damage to the design intended to hold the tower . There are many other conspiracies as to how this happened, but with the tower collapsing in its final stages, the best reason to see it as the flames slowly burned away the interior. You know that the impact of the plane cannot clearly be the reason why it collapsed because after the accident the tower had not yet collapsed but because of time. This event became one of America's nightmares and a historic event of this generation that we will all remember to this day. With his memorial in New York that we will always see, we will always remember the day of 9/11. It also increases our hope for the future, as we will be more careful about security and make America stronger. We will remember those who sacrificed their lives that day in the memorial engraving..
