What makes a bridge strong and supportive?
Suspension bridges work by using a force called tension. Tension is just pulling something tight. 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.
What gives a bridge its strength?
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.
What bridge design holds the most weight?
arch bridge
The arch bridge can hold the most weight of the three, the deck truss bridge can hold an average amount of weight, and the beam bridge could hold the least amount of weight. This experiment tested the arch, deck truss, and beam bridges to see which could hold the heaviest amount of weight.
