Question: Why Do We Need Bridge?

What is the strongest type of bridge?

Truss bridgesTruss bridges are extremely effective because they have a high strength to weight ratio.

In this experiment we have tested which type of truss bridge is the strongest, yet uses the least amount of material.

Two of the most used truss bridges are of the Pratt and Howe design..

What makes a bridge strong?

Suspension bridges are strong because the force on the bridge gets spread out. The weight of the cars or trains or horses, whatever’s traveling across it, pulls on the cables, creating tension. Those cables then pull down on the towers and also pull on the anchors on either end of the bridge, to hold up the deck.
