# What Is the Strongest Shape for a Bridge?

It is impossible to collapse a triangle without breaking one of its sides, which makes it the strongest straight-edge shape. For this reason, you will see triangles in lots of bridges. Triangle shapes in a bridge direct the weight of the bridge and the cars crossing it downward without bending.

## What Is the Strongest Shape for a Bridge?

There are many shapes that can be used for bridges, but the strongest shape is the arch. The arch is strong because it is in compression, meaning that the weight of the bridge is pushing down on the supports at the ends of the arch.

The supports are also in compression, so they are pushing up on the bridge. This creates a balanced force that keeps the bridge from collapsing.

The arch is also one of the oldest types of bridges, and it has been used for thousands of years. Some of the most famous bridges in the world, such as the Golden Gate Bridge and the Brooklyn Bridge, are arches.

There are other shapes that can be used for bridges, but they are not as strong as the arch. The truss bridge is a popular type of bridge, but it is not as strong as the arch.

The reason for this is that the truss bridge is held together by tension, meaning that the weight of the bridge is pulling on the supports at the ends of the truss.

This can cause the bridge to collapse if the supports are not strong enough. The beam bridge is also not as strong as the arch. The beam bridge is held up by compression, but the weight of the bridge is not evenly distributed
