Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider a mass-spring system with a natural frequency of 5 Hz and a damping ratio of 0.2. If a periodic force is applied at 5 Hz, calculate the amplitude at steady state.

💡 Hint: Make sure to pay careful attention to units while inputting the values.

Challenge 2 Hard

Discuss the differences in resonance effects observed in engineering versus musical applications. What design considerations are involved?

💡 Hint: Think about what happens during an earthquake versus a concert.
