- True
- False
Show hintHide hint
Consider the versatility of testing.
Question 5.
A 15-meter high tower is being tested for dynamic behavior during wind loads. The testing reveals that its first mode of vibration is at 1.5 Hz. Explain how modal testing can help improve its design.
Show hintHide hint
Consider the relationship between frequency and design.
Question 6.
