← HistoryWhich outcome occurs when Viking rope bridges experience cyclical wetting?
A)Increased tensile strength develops linearly
B)Rope fibers suffer accelerated decay✓
C)Knot strength sees consistent maximization
D)Bridge span gains resonant frequency
💡 Explanation
Cyclical wetting promotes microbial action—decomposition—in rope fibers because the Water Absorption mechanism weakens individual fiber strength; therefore, the bridge rope fibers more rapidly disintegrate, rather than strengthening or achieving resonant frequency, because the material degrades.
