← HistoryWhich outcome results when Inca suspension bridge cables elongate?
A)Increased deck cable stress✓
B)Reduced stone pillar stability
C)Decreased quipu record fidelity
D)Diminished abutment anchorage strength
💡 Explanation
Greater cable elongation leads to increased deck cable stress because the increased sag results in a greater vertical component of the cable tension. Therefore, deck cables experience greater stress, rather than abutment failure occurring primarily from anchorage integrity challenges.
