Across
- 2. any reasonably level structure designed to support a load.
- 6. triangle grooves, ridges or folds added to a structure to add strength.
- 7. a network of beams that form triangles.
- 8. this "revolutionary" bridge design allowed engineers to span large gaps, allowing ship traffic to continue and minimizing environmental damage.
- 11. this bridge spreads the force of gravity over the entire bridge.
Down
- 1. steel rods that are added to concrete to help resist tension.
- 3. a beam that is supported at one end, like a tree branch or diving board.
- 4. this bridge uses triangles to reinforce the bridge deck.
- 5. arches and domes direct compression in this direction.
- 9. a structure that looks like the top half of an egg or sphere.
- 10. a curved structure often used to support loads.
