Study Notes

Structures' stability is influenced by the location of their center of gravity, which is the point where all weight is evenly distributed in an object.
A low center of gravity is crucial for stability, as seen in examples like wide-based pyramids and well-built trees with wide trunks that can withstand strong winds.
Conversely, a high center of gravity can make a structure less stable, like the Leaning Tower of Pisa, which is prone to tipping over due to its high center of gravity.
Shifting the center of gravity can improve stability, as demonstrated in sailboats using keels to prevent tipping when wind pushes the sails.
In architecture and vehicle design, engineers consider the center of gravity carefully to enhance stability and prevent rollovers or collapses during events like earthquakes or sharp turns.
