Stability and Center of Gravity

All structures have a center of gravity (CoG)

Humans are structures so we also have a CoG.

\ Stability

The lower the CoG, the more stable the structure.

To lower the CoG we can either make the structure shorter or we can widen the base of the structure.

\ Structural Components

Arches- allows for the force to be spread equally through the curves. They take a lot less materials to create and can be creates much faster. The CoG must stay within the arches base.

\ Domes- one of the oldest types of structures. Provides shelter from elements to protect food and other valuables

\ Beams- Often shapes in the letter “I” and often made out of steel.

\ Triangles- trangles are very sturdy. You can press on them from any point and the forces will be transfered elsewhere.

\ Structural failure- structural failure is when the structure cannot withstand the forces being placed on it.
