← HistoryWhich scenario arises when ice accumulates excessively on rope bridge stays within Incan infrastructure?
A)Stayline cable tensile strength decreases✓
B)Decking planking shear stress increases
C)Anchorage point compressive stress lowers
D)Torsional cable oscillation dampening decays
💡 Explanation
Excessive ice increases the tension on the stays due to added weight, causing fatigue; therefore, the tensile strength decreases because cyclical loading exceeds material limits, rather than reduced compression which would benefit anchors.
