3Question 3.
What type of loading is described by F(t) = F₀ sin(ωt)?
- Harmonic Loading
- Static Loading
- Dynamic Loading
Show hintHide hint
Think of a wave.
4Question 4.
True or False: The amplitude of an SDOF system response increases substantially at resonance.
- True
- False
Show hintHide hint
Recall the relationship between frequency and amplitude.
Question 5.
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.
Show hintHide hint
Consider the impact of being close to the resonant frequency.
Question 6.
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.
Show hintHide hint
Think about how changing materials or shapes can alter frequency.
