Challenge Problems
Push your limits with challenges.
Question 1
A beam is subjected to a periodic load described by f(x) = f_0 sin(ωt). Derive the appropriate non-homogeneous differential equation and discuss the implications for resonance.
💡 Hint: Start by presenting the loading conditions and recall methods related to harmonic functions.
Question 2
Given the equation d²y/dx² + 2 dy/dx + 3y = e^(-x) + sin(x), solve it by applying both methods discussed: undetermined coefficients and variation of parameters, and compare results.
💡 Hint: Think systematically about how you structure each method towards finding the particular integral.
