| Resonance | Dampeners are used by bridge designers to stop what force? |
| Environmental Load | What type of load refers to the other external forces, such as wind, weather, and possible earthquake action, that affects a bridge? |
| Tension and Compression | What are the two major forces we looked at on each bridge? |
| M-shaped and A-shaped | What are the shapes associated with the two types of suspension bridges? |
| Dissipation | What is the spreading out of force or weight over a greater area so that no one area has to deal with a large amount? |
| Nature, specifically weather | This is the hardest force on a bridge because it is unpredictable and never-ending. |
| Torsion | This is a twisting or rotational force. |
| Tension | This force is defined as a force that acts to expand or lengthen the thing that it is acting upon. In other words it is a force that stretches. |
| Compression | This force is defined as a force that acts to compress or shorten the thing that it is acting upon. In other words it is a force that squeezes. |
| Resonance | This force is a vibration in something caused by an external force that is in harmony with the natural vibration of the original thing. It can be caused by wind, sound or people marching across a bridge. |
| Beam Bridge | This bridge is basically a rigid horizontal structure that is resting on two piers, one at each end. |
| Arch Bridge | This bridge is a semicircular structure with abutments on each end. |
| Suspension Bridge | This bridge is a bridge in which cables or ropes are strung across an obstacle, such as a river, and the deck is suspended from these cables. |
| Trusses | These are a pattern of triangles and additional beams used to spread the forces on a beam bridge. |
| Beam, Arch and Suspension | The three major types of bridges are_____________________. |
| Two bridge supports | The span of a bridge is defined as the distance between __________________. |
| Passage over obstacles | The purpose of a bridge is to provide ___________________. |
| 800-1000 feet | How far can an arch bridge safely span? |
| 7000 feet | How far can a suspension bridge safely span? |
| 200 feet | How far can a beam bridge safely span? |
| Suspension Bridge | Classic and Cable-stayed are both a type of what bridge? |
| Load | What is defined as any force, such as weight, that affects a bridge? |
| Dead Load | What type of load refers to the weight of the bridge itself? |
| Live Load | What type of load refers to the weight of the traffic the bridge will carry? |
| Deck Truss and Through Trusss | What are the two types of trusses? |
| Deck truss | In this type of truss bridge, the supporting trusses are placed below the roadway |
| Through truss | In this type of truss bridge, the supporting trusses are placed above the roadway |
