TED-Ed: Epic Engineering: Building the Brooklyn Bridge | Alex Gendler

In the mid-19th century, suspension bridges in Europe were failing, prompting John Roebling to propose a hybrid bridge over New York's East River. His design combined elements of suspension and cable-stayed bridges, enhancing stability and reducing weight. Despite Roebling's death, his son Washington and daughter-in-law Emily continued the project, overcoming challenges like decompression sickness and faulty materials. After 14 years, the Brooklyn Bridge opened in 1883, becoming an engineering marvel and a symbol of New York City.

What was the main reason for the failure of suspension bridges in Europe during the mid-19th century?

• Lack of skilled engineers

• Poor construction materials

• Fraying of industrial cables during bad weather

• Inadequate design of the decks

Which two types of bridge designs did John Roebling combine for the Brooklyn Bridge?

• Girder and arch bridges

• Arch and beam bridges

• Suspension and cable-stayed bridges

• Truss and cantilever bridges

What innovative technology was used to build the tower foundations of the Brooklyn Bridge?

• Pneumatic caissons

• Steam-powered drills

• Hydraulic lifts

• Electric cranes

Who played a crucial role in managing the Brooklyn Bridge project after Washington Roebling became ill?

• The city officials

• A team of engineers

• Emily Roebling

• John Roebling

What was a major issue discovered with the bridge's cables during construction?

• They were made of faulty wires

• They were too heavy
