Exam-style question
Try this first
Explain how resonance can be applied in the design of a bridge to ensure safety and stability.
Model answer
What a good answer should say
- Resonance occurs when the natural frequency of a structure matches the frequency of external forces, leading to increased amplitude of oscillations.
- In bridge design, engineers must consider the natural frequency of the bridge to avoid resonance with wind or traffic vibrations, which could cause structural failure.
Explanation
Why this works
This answer demonstrates understanding of resonance and its implications in engineering contexts, testing the application of physical principles to real-world scenarios.
