"Crossing Over"

 

This picture illustrates a brigde over a body of water. A bridge illustrates concepts of physics related to force and free body diagrams. The bridge must be able to sustain the force of gravity and the weight of the cars passing on the bridge, ensuring the bridge remains intact for cars to cross over the water and for boats to travel underneath. If the force on the bridge is not correctly distributed over the entire bridge, the bridge will collapse. This picture features a specific type of bridge called a compression-arch suspended deck bridge. The compression-arch suspended deck bridge is a modern type of arch bridge made of light and strong tensile materials. The arch in the bridge works to sustain the force by compressing and transferring all of the weight into the supports which exist at either end of the bridge and eventually into the ground.
