← HistoryWhich threat increased for Inca rope bridges during wetter highland seasons within the Andes?
A)Increased structural deck oscillation✓
B)Decreased pedestrian weight capacity
C)Accelerated abutment settling velocity
D)Enhanced anchor corrosion resistance
💡 Explanation
Increased moisture saturates the natural fiber ropes, decreasing tension; the bridge's natural frequency lowers, because of increased inertial mass leading to resonance when excited by wind or pedestrians, therefore leading to oscillations, rather than improving stability, as decay accelerates
