← ScienceWhich outcome occurs when rapid cycling causes over-extension spring fatigue?
A)Decreased energy storage of the spring✓
B)Increased spring constant linearly overtime
C)Resonance amplification from applied forces
D)Increased tensile strength within spring coil
💡 Explanation
Decreased energy happens during fatigue cycling because micro-cracks propagate, reducing the material's ability to store elastic energy due to crack propagation; therefore the decreased capability results, rather than increased strength, reflecting accumulated damage.
