Teacher Reference Guide
The Golden Gate Bridge is one of the most iconic suspension bridges in the world, and understanding its design can teach students the fundamentals of engineering. A suspension bridge is supported by cables that are anchored at both ends and suspended from towers. These cables distribute the weight of the bridge and the vehicles traveling across it. Anchorages, massive structures at each end of the bridge, hold the cables in place and help transfer the load into the ground, ensuring the bridge’s stability.
Two key forces are at play in the construction and maintenance of suspension bridges: tension and compression. Tension is a pulling force that stretches materials, such as the suspension cables. These cables bear much of the weight and stress on the bridge. Compression, on the other hand, is a pushing force that compacts or squeezes materials. The bridge’s towers experience compression as they bear the downward force of the cables and distribute it into their foundations. These two forces work together to keep the bridge balanced and structurally sound.
Another critical consideration for bridge stability is wind load. Wind load refers to the force exerted by wind on a structure. Engineers must account for this force to ensure that bridges like the Golden Gate can withstand high winds without swaying excessively or becoming damaged. The design of suspension bridges often includes aerodynamic features to reduce wind resistance and enhance stability.
In this lesson, students will explore these concepts through three key settings in the escape room. In the Engineer’s Workshop, they will learn the basic components of a suspension bridge and how they work together. Moving to the Suspension Tower, students will delve deeper into the roles of tension and compression, understanding how these forces interact to support the bridge. Finally, in the Bay Maintenance Substation, students will apply their knowledge to practical challenges, considering how engineers maintain the bridge and address issues like wind load and structural integrity.
Students should watch the Adventure Guide video before beginning the escape room to familiarize themselves with these concepts. If they need help at any point during the escape room, they can click the Adventure Guide button on each question page to revisit the video. By the end of the lesson, students will understand the key engineering principles that keep suspension bridges like the Golden Gate standing strong, while also applying critical thinking and problem-solving skills to protect the bridge from a fictional disaster.
