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.
