Question 1.
What is one use of frequency analysis in structural health monitoring?
Show hintHide hint
Think of how vibrations might change in response to physical changes.
Question 2.
How can frequency analysis assist in environmental monitoring?
Show hintHide hint
Consider what regular patterns in weather data might imply.
3Question 3.
What does a shift in the resonant frequency of a structure indicate?
- No change in structural integrity
- Potential damage or changes in stiffness
- An increase in mechanical efficiency
