- Strong ocean currents.
How does the Golden Gate Bridge stay up?
Longest suspension bridge in the world The Golden Gate Bridge is a suspension bridge, meaning it relies on cables and suspenders under tension along with towers under compression to cross a long distance without any intermediate supports.
What kind of force do the cables of the Golden Gate Bridge provide tension or compression?
friction forces
Which bridge is the most expensive?

How long is a modern suspension bridge?
Suspension bridges are typically ranked by the length of their main span. These are the ten bridges with the longest spans, followed by the length of the span and the year the bridge opened for traffic: Akashi Kaikyō Bridge (Japan), 1991 m (6532 ft) – 1998. Yangsigang Bridge (China), 1700 m (5577 ft) – 2019.
How much does the suspension bridge cost?
The typical cost of suspension bridges ranges from $8,000 to $9,000 US per square meter. Of all the bridge types in use today, the suspension bridge allows for the longest spans. At first glance the suspension and cable-stayed bridges may look similar, but they are quite different.
What forces act on a suspension bridge?
The main forces in a suspension bridge are tension in the cables and compression in the towers. The deck, which is usually a truss or a box girder, is connected to the suspension cables by vertical suspender cables or rods, called hangers, which are also in tension.
What is the oldest truss bridge?
the Kapellbrücke
How much can a truss bridge hold?
Typically, superhighways are designed and built to handle up to 80,000 pound loads, continuously.
