Which structural weakness results when a wooden ship experiences differential swelling?

💡 Explanation

Hogging or sagging arises because differential moisture absorption induces uneven expansion, leading to longitudinal bending stress, and therefore hull deformation, rather than corrosion alone as the wood's behavior dominates over electrochemical processes.
