Challenge Problems
Push your limits with challenges.
Question 1
Given a damped system described by y(t) = e^(-t/5)(3cos(2t) + 4sin(2t)), identify the damping factor and angular frequency.
💡 Hint: Compare to the standard form y(t) = e^(-αt)(Acos(ωt) + Bsin(ωt)).
Question 2
A structure experiences damped harmonic motion. How would you model the response to an external force over time using complex exponentials?
💡 Hint: Include the effects of initial conditions in your constants.
