← HistoryWhich consequence results when timbers in a Viking longship experience differing moisture levels?
A)Seawater bacterial anaerobic sulfide cracking
B)Hull twist induces rudder jamming✓
C)Sodden cords cause sail collapse
D)Rope embrittlement weakens rigging
💡 Explanation
Hull twisting occurs because differential swelling introduces uneven stresses, inducing the mechanism of structural deformation due to misaligned support points; therefore, the rudder jams; rather than uniform expansion only causing increased weight or sail issues.
