← HistoryWhich consequence reduces Andean Inca suspension bridge lifespan due to increased stress?
A)Decking material's fastener fatigue
B)Main cable's creep deformation
C)Stone anchor's seismic cracking
D)Fiber rope's abrasive deterioration✓
💡 Explanation
The rope's abrasive deterioration occurs from windblown dust and grit sawing through the fiber; because the Suspension bridge uses natural materials this abrasion weakens the fibers, therefore shortening the lifespan, rather than cable creep which affects metal cables.
