## Q. Why is an arch stronger than a beam?

An **arch** bridge is **stronger than a beam** bridge, simply because the **beam** has a weak point in the center where there is no vertical support while **arches** press the weight outward toward the support. … **Arch** bridges, meanwhile, have been used to cover very long distances, with up to 800 feet for a single **arch**.

## Q. What is the most appealing shape?

The most aesthetically pleasing images are all based on **the golden ratio**. **The golden ratio** is, put simply, a rectangle a little more than 1.

## Q. Is a circle stronger than a square?

Yes. **Circles** are much **stronger than** squares due to the even weight distribution. Squares have weak points, in the center between each corner. A steel pipe will handle much more weight **than** a steel **square** tube.

## Q. What angle is the strongest?

45 **degrees** is the strongest brace angle for a **right-angle triangle**, but the absolutely strongest is an **equilateral triangle** with three 60 **degree** angles.

## Q. Is a hexagon stronger than a triangle?

The **hexagon** is not the **strongest** shape, the **triangle** is. … If you have a **triangle**(3 straws you can not change its shape without breaking or bending a straw. If you have more sides, a little pressure will change the shape although the straws do not bend. The **hexagon** is made of **triangles**.

## Q. Why triangles are used in bridges and towers?

Before **triangles** were **used in bridges**, they were weak and could not be very big. … Architects use many **triangles** in **bridges**.

## Q. What is the best shape for a bridge?
