← HistoryWhich consequence results when Inca suspension bridge cables degrade?
A)Deck sags; cable Tensile Strength✓
B)Towers buckle; compressive loading
C)Anchors slip; bedrock fracturing
D)Wind amplification; harmonic oscillation
💡 Explanation
The walking deck will sag because reduced Tensile Strength in historically natural fiber cables causes increased elongation under load; therefore the road dips, rather than towers failing in compression or geological anchors slipping due to shearing forces.
