The Ways the Bridge Vibrates
The Bridge has many modes of vibration, or ways in which it can move in response to wind or earthquakes. This mechanical hands-on exhibit lets visitors “excite” (shake) the model in varying ways to see how it responds. The main span between the towers can sway sideways, back and forth like a swing, or it can take on a snake-like pattern of vertical or horizontal displacement depending on the rate at which it is moved. In the try-out of the prototype at the Bridge, it also served the useful purpose of providing visitors with photo opportunities and activities when the Gate was socked in with thick fog.
STATUS: This exhibit is currently on display near the flagpole area.
