← HistoryWhich consequence results when corrosion compromises Viking rope bridge integrity?
A)Increased catenary sag develops✓
B)Anchorage points experience greater shear
C)Timber decking endures increased load
D)Overall bridge stiffness inherently lessens
💡 Explanation
Increased catenary sag develops because rope strength reduces due to the corrosion mechanism induced weakening of fibrous materials; therefore bridge stability is lost, rather than immediate shear failure occurring (which depends on load and anchor details).
