Bridges

6. A pushing or pressing force.
7. The tallest vertical structures of a suspension bridge that support the main cables.
8. itself.
10. Beam A thin beam that is more susceptible to bending.
13. like a deep beam and the triangles help to resist the forces of tension and compression.
14. The bottommost portion of a pier or tower that secures the bridge underground.
16. Beam A thick beam with greater ability to resist bending.
17. The massive structures that secure the main cables of a suspension bridge, creating a tension force within the main
19. The measurement of distance between two supports in a bridge.
21. The bridge roadway.
22. The vertical cablesof a suspension bridgethat suspend the roadway from the main cables.

1. structurein place.
2. A horizontal piece of structure supported on both ends that spans across a distance, often supported by vertical
3. The central stone of a masonryarch. Typically larger or decorated to represent its role of locking and securing the
4. A curved, symmetrical structure, often made from masonry (cut stone) or steel.
5. Wedge-shaped blocks that are used to build a stone or brick arch. Voussoirs work in compression, pressing on one
9. A pulling or stretching force.
11. Cables The large cables of a suspension bridge that are held by the anchorages and supported by the towers.
12. Load The force on a structure that can change or move. This force may be caused by the movement of cars and trains or
15. A structure that is usually built from straight pieces of metal or wood to form a series of triangles. This structure
16. Load A force on a structure that is relatively constant. This is often the weight of the materials used to construct the
18. The massive structures at the end of a bridge that help to resist the lateral forces of a bridge and connect it to the
20. A vertical support that carries the weight of the bridge down to the pier’s footing and into the ground.
23. natural elements such as wind, rain, snow, earthquakes, etc.
