← HistoryWhich consequence resulted when suspension bridge cable strands corroded during the Industrial Revolution?
A)Anchor point shear forces increased✓
B)Deck oscillation frequencies synchronized
C)Material yield ratio decreased
D)Shear stress delamination accelerated
💡 Explanation
Increased corrosion reduced cable tensile strength, diminishing the suspension bridge's load capacity; the weakened cables experienced larger tensile forces, which then increased anchor point shear. This is because load redistribution created greater point stresses, therefore bridge failure risk grew rather than solely cable snapping.
