4Question 4.
True or False: FEA can only be used after fabrication.
- True
- False
Show hintHide hint
Think about design processes and their stages.
Question 5.
Design a MEMS device that requires analysis of both stress and vibration. Describe how you would set up an FEA simulation for this device, including the parameters you would consider.
Show hintHide hint
Consider both mechanical forces and dynamic aspects.
Question 6.
