Increased torsional stress occurs within Viking longship hulls primarily through which mechanism?

💡 Explanation

The deformation through hogging and sagging places stress on ship hulls because the buoyant forces conflict with moments arms, thereby causing the structure to twist from its length rather than direct water pressure shearing the rivets.
