Challenge Problems
Push your limits with advanced challenges
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.
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.
