← HistoryWhich consequence results when differential expansion stresses rivets beyond yield strength in longships?
A)Sheathing plank detachment increases steadily✓
B)Rope rigging fraying becomes catastrophic
C)Sail cloth tearing initiates rapidly
D)Hull twisting prevents further travel
💡 Explanation
Sheathing detachment increases because differential thermal expansion induces thermal stress; beyond the fasteners' yield strength, plastic deformation via RATCHETING occurs, causing loosening. Therefore, planking separates rather than rigging fraying, sail tears, or immediate hull twisting due to incremental, repetitive failures.
