Question 1

What does decoupling achieve in structural dynamics?

  • Makes equations more complex
  • Simplifies the analysis
  • None of the above

💡 Hint: Think about whether the process makes things easier or harder.

Question 2

True or False: Modal superposition allows us to analyze the total response of a system by summing individual mode responses.

  • True
  • False

💡 Hint: Recall how we can combine steps in a calculation.
