Challenge Problems
Push your limits with challenges.
Question 1
You have an SDOF system with a natural frequency of 3 rad/s. An applied force oscillates at 3.5 rad/s with an amplitude of 100 N. Discuss the potential impact of this frequency difference and calculate the expected amplitude of the response.
💡 Hint: Consider the impact of being close to the resonant frequency.
Question 2
Explain how to adapt your design if the expected loading frequency is too close to the natural frequency of your SDOF system. Provide an example.
💡 Hint: Think about how changing materials or shapes can alter frequency.
