← HistoryWhich behavior becomes increasingly significant when timber longship hull stiffness decreases?
A)Hogging and sagging undulations✓
B)Torsional snap-through buckling
C)Longitudinal compression yielding
D)Transverse frame shear breakage
💡 Explanation
When longships lost hull timber stiffness, wave forces induce bending across the hull via global bending, therefore increasing hogging and sagging distortions, rather than breakage. Torsional and compression effects are second order because bending moment dominates failures.
