The force on this bridge

Compression and Tension- When something pushes down on the beam, the beam bends. Its top edge is pushed together, and its bottom edge is pulled apart.

The beam bridge consists of a horizontal beam supported at each end by piers. The weight of the beam pushes straight down on the piers. The farther apart its piers, the weaker the beam becomes. This is why beam bridges rarely span more than 250 feet.
