The Golden Gate Bridge
By: Rachel Lee
It is used in this location because a suspension could withstand brutal winds, tide, fog, and earthquakes. Stood for 27 years. Sturdy. Long distance for a cheap cost.
Triangles of the Golden Gate Bridge
Where: Bottom of the bridge, right below the road. Congruent in size and shape
Why:
- Uses geometric principles of rigidity to make sturdy while using little material
- Not possible to change the angle of vertex without changing the length of side (vice versa)
Location and Structure
- Design consists on suspension, truss arches, and truss causeways
- Material used: steel
