Name all of the technological innovations that were mentioned in class today. Provide a brief explanation of all four.
What is:
1. Method of weaving steel wire cables - provided extra stability and durability for the bridge, was discovered by the chief engineer, John A. Roebling
2. Pneumatic caissons - these were watertight, airtight chambers at the bottom of the East River; they were used to anchor the bridge and acted as the foundation of the structure
3. coated with metal zinc - to prevent rusting
4. illuminated with electric lights - drew attention to the landmark, especially at night; furthered the admiration of residents and people from all around the world towards it
