Step 1
Outline one method which may be used to protect the steel cables on the bridge from corrosion.
Answer
One effective method to protect the steel cables from corrosion is by galvanizing. This process involves coating the steel with a layer of zinc, which serves as a protective barrier against moisture and environmental factors that cause rust. Galvanizing not only provides a physical barrier but also sacrificial protection, as zinc will corrode before the underlying steel does, prolonging the lifespan of the steel cables.
