← HistoryWhich outcome results when inadequately seasoned wood makes up the structural cables of a late Qing dynasty suspension bridge?
A)Increased cable tensile bending
B)Onset of cable material creep
C)Induced sympathetic resonance oscillation
D)Decreased bridge structural stiffness✓
💡 Explanation
Decreased bridge structural stiffness will occur because moisture loss causes wood shrinkage creating slack within the cable strands via wood's dimensional changes; therefore flexibility increases, rather than increased tension due to creep properties in better seasoned samples.
