What is the strongest design for a toothpick bridge?

The strongest toothpick bridges have very big ratios of their own weight to the maximum weight they can handle. Organizers of most bridge-building contests rank these bridges, highly. It should also have the capacity to withstand tension, that is, the force which tends to pull apart or elongate the bridge.

What is the strongest type of bridge?

A truss bridge is the strongest kind of bridge. It combines materials in a simple and efficient way that reduces and spreads out loads over a large area. They flex less than other kinds of bridges and provide greater stability even in extreme weather or traffic.

Even though elaborate school-grade toothpick bridges (for example of fully arched design) can weigh over a pound, smaller bridges in the range of 100 grams can carry the load of four or five fully solid bricks!

What makes a strong bridge?

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 is the strongest bridge shape?

The overall shape of many bridges is in the shape of a catenary curve. The catenary curve is the strongest shape for an arch which supports only its own shape. Freely hanging cables naturally form a catenary curve. The hexagon is the strongest shape known.

The objective of this project was to build a bridge using nothing but school glue and toothpicks. Our teacher have us credit for just simply building a bridge but gave us extra points for every pound it held with the maximum being 30 pounds.

How do you make a bridge out of wax paper?

Spread wax paper over the sketch and trace out the drawing on the wax paper. Put the toothpicks over the pencil marks on the wax paper and glue them together. You can also insert the toothpicks into marshmallows which can secure the junctions of your bridge. Hold the framework upright. One side of your bridge is made.

How to make a bridge out of graph paper?

Step-by-Step Instructions Sketch the model of your bridge on the graph paper. It’s recommended to give a square foundation to your model, because such a base will make the bridge strong.
