Science kits are back at the York County Public Library! This month's kit explores engineering and bridge design. Different shapes have different strengths. So, put on your thinking cap and think about what makes a strong bridge and what makes a weak bridge.
The strongest type of bridge is a stone arch. However, these bridges are expensive to build and are limited in size and height. They are not the best choice when building over a very wide river that has a lot of big boat traffic. A suspension bridge is an economical way to build and they are easy to maintain and update over time. However, they must be built in specific way. Take a look at this video of a poorly designed suspension bridge:
