← HistoryWhich mechanism allowed 18th-century wooden sailing ships to withstand hull stress within limits?
A)Iron straps distributing tension✓
B)Copper sheathing avoiding corrosion
C)Oakum caulking preventing leaks
D)Tar coating reducing biofouling
💡 Explanation
When a wooden ships experiences wave-induced stress, iron straps distribute tension because they are fastened along the ships hull, preventing the hull from splitting or deforming excessively. Therefore, iron straps provided hull reinforcement, rather than corrosion resistance, leak prevention, or biofouling reduction, which address other failure modes.
