Which structural weakness commonly arose during the transition from wooden to iron shipbuilding during the 19th century era?

💡 Explanation

When iron hulls were fastened to existing copper or bronze components, or dissimilar metal rivets were used, galvanic corrosion occurred because seawater acts as an electrolyte between the different metals, accelerating corrosion of the more anodic metal. Therefore electrolytic corrosion results, rather than brittle fracture, shear failure, or reduced buoyancy which involve different material properties or design constraints.
