(a) Write down the dynamic equation of force equilibrium in matrix/vector form and identify each term in that equation. b) Discuss the differences between (i) frequency and (ii) time domain dynamic structural analyses. Which of these two approaches should be used for nonlinear analyses (explain why) and suggest why it is always valuable to first undertake a frequency analysis.
