For example, consider the compression and tension stresses on a beam bridge, such as the bridge shown in the photo. Bridge foundations have to be carefully selected and constructed since they will bear the bridge and the vehicle loads. Suspension bridges that carry cars tend to bear the same loads all day long, though, often sited in windy estuaries, they also have to endure squalling gusts of wind, which can set up a twisting force, called torsion, in the bridge deck. These differences are important when deciding what kind of bridge would work best in any given situation. Early suspension bridges were made with twisted grass. The basic structural components of a suspension bridge system include stiffening girders/trusses, the main suspension cables, main towers, and the anchorages for the cables at each end of the bridge.
