← HistoryWhich consequence results when ice accumulates excessively on a historical rope bridge?
A)Increased tensile cable snapping✓
B)Decreased deck plank deflection
C)Enhanced abutment pier stability
D)Reduced wind-induced oscillation
💡 Explanation
Increased ice mass leads to higher tensile stress on the ropes due to increased weight from gravitational FORCE and deformation. This results in tensile cable snapping failure modes, because the ropes ultimate stress is locally overcome; therefore, failure modes are likely, rather than enhanced stabilizing.
