Question 1

What is the equation for a damped harmonic oscillator?

m x¨ + b x˙ + k x = 0
m x¨ + k x = F
F = - k x

💡 Hint: Think about how damping changes the oscillator's behavior.

Question 2

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A mass-spring system oscillates with a natural frequency of 5 Hz and a damping ratio of 0.5. What is the damped frequency and how does it compare to the natural frequency?

💡 Hint: Use the given formula for damped frequency.

Challenge 2 Hard

A bridge anticipates resonance with wind currents during a storm. The natural frequency is 1 Hz, and the wind generates a frequency of 1.1 Hz. Explain what precautions might engineering teams take.

💡 Hint: Think about stability in oscillatory systems.
