TED-Ed: Building the impossible: Golden Gate Bridge | Alex Gendler

The video discusses the construction of the Golden Gate Bridge, highlighting the challenges faced by engineers Charles Ellis and Joseph Strauss. Initially, the project faced opposition from various groups and skepticism from engineers. The design evolved from a cantilever to a suspension bridge, thanks to innovations in steel manufacturing. Construction involved significant challenges, including building underwater foundations and ensuring worker safety. Despite setbacks, the bridge was completed, with its iconic International Orange color chosen over the Navy's proposal.

What was one of the main concerns of the military regarding the construction of the Golden Gate Bridge?

• It would block naval routes.

• It would be too costly.

• It would make the harbor more vulnerable.

• It would increase traffic congestion.

What type of bridge did Strauss initially plan to build across the Golden Gate Strait?

• Cantilever bridge

• Arch bridge

• Beam bridge

• Suspension bridge

Why was the suspension bridge design chosen over the cantilever bridge?

• It was easier to construct.

• It required fewer materials.

• It was more flexible and resilient to winds.

• It was cheaper to build.

What was a major challenge in constructing the South Tower of the Golden Gate Bridge?

• Transporting materials

• Finding a stable foundation

• Building underwater

• Dealing with strong winds

What safety measure did Strauss implement to protect workers during construction?

• Regular safety drills

• Safety nets below the towers

• Protective goggles

• Mandatory life jackets

What tragic event occurred during the construction of the Golden Gate Bridge?

• A fire broke out on the bridge.

• A major storm delayed construction.

• A ship collided with the bridge.

• A scaffolding platform fell, resulting in worker fatalities.

What color was ultimately chosen for the Golden Gate Bridge, and why?

• Black and yellow for tactical reasons

• International Orange to complement the natural surroundings

• Silver to reflect sunlight

• Blue to match the water
