Challenge Problems
Push your limits with advanced challenges
A vibration system has an input amplitude of 5 mm, and the output amplitude is 1 mm. Calculate transmissibility and determine if the system is effective or amplifying.
💡 Hint: Use the formula T = output/input.
Describe a scenario where the frequency ratio is fixed, but output amplitude suddenly increases. What design considerations should be made?
💡 Hint: Think about how to shift the vibrations away from the current operating point.
