← HistoryWhich risk increases when Inca rope suspension bridges experience high foot traffic?
A)Anchorage stone cracking
B)Bridge deck oscillation
C)Knot slippage likelihood✓
D)Material fiber hydration
💡 Explanation
Increased foot traffic on Inca suspension bridges raises the chance of knot slippage because of increased dynamic tensile stress on the ichu grass ropes; therefore knot security degrades rather than structural members failing, due to construction limitations.
