Across
- 3. supported roadway on a bridge
- 5. a force applied or distributed over an area
- 7. a force that causes parts of a material to slide past one another in opposite directions
- 8. Bridge a curved structure that converts the downward force of its own weight, and any weight pressing down on top of it, into an outward force along its side and base
- 10. a rigid, usually horizontal, structural element
- 11. a bridge or channel for conveying water, usually over long distances
- 14. a change in shape from normal or desired
- 16. to bend under compression
- 19. the distance a bridge extends between two supports
- 20. Bridge a simple type of bridge, composed of horizontal beams with vertical posts
- 23. a stretching force that pulls on a material
Down
- 1. A structure built over an obstacle, such as a river or a road.
- 2. a push or pull; any action that tends to maintain or alter the position of a structure
- 4. characteristic of a structure that collapses or deforms under a realistic load
- 6. ability to resist collapse and deformation; stability (n.) characteristic of a structure that is able to carry a realistic load without collapsing or deforming significantly
- 9. a vertical, structural element, strong in compression
- 12. an action that twists a material
- 13. (n) a structural support; (v) to strengthen and stiffen a structure to resist loads
- 15. a rigid frame composed of short, straight pieces joined to form a series of triangles or other stable shapes
- 17. a pressing force that squeezes things, or a thing, together
- 18. weight distribution throughout a structure; loads caused by wind, earthquakes, and gravity, for example, affect how weight is distributed throughout a structure
- 21. a device connecting two or more adjacent parts of a structure; a roller joint allows adjacent parts to move controllably past one another; a rigid joint prevents adjacent parts from moving or rotating past one another
- 22. ability to resist deformation when subjected to a load
