← HistoryWhich failure mode increases as Viking rope bridges absorbed kinetic energy?
A)Catenary sag becomes excessive
B)Rope fibers experience creep✓
C)Anchor points experience shear
D)Decking planks suffer delamination
💡 Explanation
Creep in rope fibers increases because the sustained tension from repeated impacts stretches the material over time; therefore fiber damage accumulates rather than catastrophic failure typical of sudden tension or a shear failure from the anchors, because there is some flexibility.
