Physics of 9/11

The physics of 9/11 involves the structural mechanics of the Twin Towers and the effects of impact and fire. When the planes struck, the force compromised the steel and concrete structures. The intense heat from the resulting fires weakened the steel beams, causing them to lose their strength. This combination of impact damage and heat-induced weakness led to a progressive collapse. Ultimately, the buildings could not withstand the additional loads, leading to their catastrophic failure. Understanding these dynamics highlights the importance of engineering in building design, particularly regarding safety measures against extreme events.
