← HistoryWhich risk increases when bronze saw-teeth experience extensive cyclic loading during ancient lumber harvesting?
A)Reduced soil water tension
B)Accelerated anaerobic decomposition
C)Progressive ductile crack propagation✓
D)Decreased vegetative carbon sequestration
💡 Explanation
Fatigue cracking increases in bronze saws because repeated stress causes progressive ductile crack propagation at imperfections, therefore the saw will fracture much sooner rather than experiencing uniform wear under constant load.
