← HistoryWhen overloading a historical Viking ship's rigging, which failure propagates due to creep?
A)Rope fibers experience progressive extension✓
B)Sailcloth tears unpredictably mid-voyage
C)Frame joints suddenly lose water-tightness
D)Mast fractures from cyclic wind stress
💡 Explanation
Progressive overloading causes rope fibers to slip past each other, a process called creep, because load exceeds material yield thresholds; therefore, fibers extend over prolonged use rather than sail tearing or immediate rupture of masts, whose failures involve different mechanisms.
