History

Which structural problem rapidly escalated due to wind-induced resonance affecting early suspension bridges constructed with wrought iron chains?

A)Decreased fatigue life
B)Increased tensile strength
C)Formation of surface rust
D)Enhanced material flexibility

💡 Explanation

Reduced fatigue life occurred because cyclic loading caused by the aeroelastic flutter amplified stress at chain links. This weakened the chains, therefore accelerating structural failure rather than increased strength; different materials would have resisted fatigue longer.
