It is found that inherent frequencies are much larger than pumping frequencies and resonance cannot emerge before and after optimization. Fatigue breakage is caused by overload mainly.

结果发现优化前后支架的固有频率都远大于激励频率，不会产生共振，疲劳破坏主要由载荷超重引起的。

Hayek's view has resonance for anyone who feels uneasy about governments bailing out bankers and central banks pumping hundreds of billions of dollars into the economy.
