The crane whose body is closest to the soil represents a wide diagonal line that appears to be increasing from right…

The static load of the bridge is the bridge itself, and the weight of its members and components. This is created by the force of gravity pulling on the members of the bridge. The dynamic load moves and changes, such as traffic, people, wind. It is created…
