What is the best material to use to build a bridge?

Best Material for Bridges: Steel Its strength and permanence are ideal for long-lasting structures, like bridges. The use of steel for bridges replaced earlier materials such as wood, concrete and stone.

What makes a bridge stable?

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.

How do you build a bridge over a creek?

The material or component conducts heat better than the insulation and therefore effectively forms a bridge allowing heat to transfer between the inside and the outside.
