Challenge Problems
Push your limits with challenges.
Question 1
A pendulum experiences free vibrations. If the damping ratio is 0.5, what impact does this have on the system's oscillations compared to critical damping?
💡 Hint: Think about how damping affects the speed of return to rest.
Question 2
An engine operates at a speed where resonance is suspected. If the natural frequency of vibration is calculated to be 25 Hz, what steps can an engineer take to avoid failure?
💡 Hint: Consider the relationship between frequency and speed in your solution.
