Challenge Problems
Push your limits with challenges.
Question 1
A tuning fork resonates with sound waves at 440 Hz. If a sound wave at 440 Hz is directed at it, what will the amplitude of the sound become? Discuss how this system behaves as it reaches resonance.
💡 Hint: Recall how musical instruments amplify sound.
Question 2
Consider a bridge exposed to periodic traffic vibrations. If the natural frequency of the bridge matches these vibrations, what problems might the structure face, and how should engineers respond?
💡 Hint: Think about historical examples of bridge collapses due to resonance.
