No, the second tower (the one which was hit by the second plane) collapsed a few minutes after the first tower.
The forces acting upon the twin towers were primarily gravity, wind loads, and the impact of the airplanes on 9/11. These forces caused structural damage and ultimately led to the collapse of the towers.
The Twin Towers at the World Trade Center collapsed on September 11, 2001, after being struck by hijacked airliners. The impact of the planes, combined with the ensuing fires, weakened the buildings' structures, causing them to ultimately collapse.
No, it was actually the heat from the fires that weakened the steel in the structures. The resulting "pancake" collapse was a result of the same thing that happens when you knock over a row of dominoes - the failure of the floor where the planes hit (due to the above weakened steel supports) caused it to fall directly down on the floor below, which could not withstand such an impact, and it failed, hitting the floor below, etc.

The collapse of the Twin Towers on September 11, 2001, was caused by the impact of two hijacked planes (American Airlines Flight 11 and United Airlines Flight 175) crashing into the buildings, which weakened the structures, combined with the intense heat from the resulting fires that caused the steel framework to lose its structural integrity.
2 planes with terrorists wanted to destroy the twin towers
