Which outcome occurs due to hogging stresses in a wooden ship's hull during construction without adequate support?

💡 Explanation

When a long wooden ship is supported only at its ends during construction, hogging results because the weight of the unsupported middle sections causes tensile stress at the keel and compressive stress at the upper decks. Therefore keel fracture amidships occurs, rather than deck flattening, stern frame buckling, or bow planking separation which involve localised failures and/or require insufficient local fastening.
