Bridges Mr. O’Rourke Technology. What is a Bridge? A structure built to span a valley, road, body of water or other physical obstacle for the purpose.

There are more than 500,000 bridges in the United States!

 The biggest difference is the distance they can cross in a single span.  A modern arch can safely span up to 800 or 1,000 feet.  While a suspension.

Examining Forces on Bridges.  At any given time, two main forces act upon a bridge: compression and tension.  It is the job of engineers to design bridges.

Beam Bridge – a horizontal beam supported at both ends.

Span – the distance that a bridge extends between 2 supports.

Load – a force that acts upon a structure.

2 Types of Loads Dead Load – the weight of the structure. Live Load – the weight of things on the structure. Examples:

Take a look at this picture to see how the load is affecting the structure. There are two main forces at work here…

Compression - the force that presses down on the top of the bridge Compression - the force that presses down on the top of the bridge. Tension - the force that presses outward on the bottom of the bridge.

Hopefully this information will be useful when designing and constructing your bridge. THE END! 
