← HistoryIn 18th-century drydock ship construction, which risk increases most when timber seasoning falls below optimum levels before planking?
A)Increased hull twisting forces accumulate✓
B)Reduced heat stress on structural members
C)Optimal galvanic isolation achieved
D)Improved propeller cavitation performance results
💡 Explanation
Increased hull twisting occurs because inadequate timber seasoning causes uneven wood shrinkage across planking after assembly and repeated wetting. This induces internal stresses throughout the hull because constrained shrinkage generates cumulative twisting forces, rather than uniform stress. Therefore, hull integrity decreases.
