Why Twin Towers Collapsed?
On September 11th, 2001, the world watched in horror as the Twin Towers of the World Trade Center in New York City collapsed. This tragic event left thousands of people dead and changed the course of history. The destruction of the Twin Towers had a tremendous impact on the United States and the world. But why did the Twin Towers collapse?
The cause of the collapse of the Twin Towers was the result of a combination of factors. The primary cause was the terrorist attack on the Twin Towers. On September 11th, two hijacked planes were flown into the towers, causing extensive structural damage. The impact of the aircraft caused the fires to spread quickly throughout the buildings, weakening the steel structure and causing a progressive collapse.
In addition to the damage caused by the planes, the Twin Towers were also weakened by the intense heat of the fires. The steel used in the construction of the Twin Towers was designed to withstand average fire temperatures. Still, the fires from the plane fuel and other combustible materials were far hotter than usual, reaching temperatures of up to 1800 degrees Fahrenheit. This caused the steel to weaken and eventually gave way, leading to the towers’ collapse.
The buildings’ design was the other contributing factor to the Twin Towers’ collapse.
