5min 5sec @TEDEd clip - Why doesn’t the Leaning Tower of Pisa fall over? - Alex Gendler
text from youtube "Dig into the 800 year history and architecture of the Leaning Tower of Pisa and find out what gives the tower its infamous tilt.
--
In 1990, the Italian government enlisted top engineers to stabilize Pisa’s famous Leaning Tower. There’d been many attempts during its 800 year history, but computer models revealed the urgency of their situation. The tower would topple if it reached an angle of 5.44 degrees— and it was currently leaning at 5.5. What gives the tower its infamous tilt? Alex Gendler explores the monument's history.
Lesson by Alex Gendler, directed by Aim Creative Studios."
