Given a harmonic oscillator represented by the equation q¨(t) + 25q(t) = 5, solve for q(t) using Duhamel’s Integral given an initial condition of q(0)=0 and q˙(0)=0.
💡 Hint: Map out the steps of Duhamel’s process carefully, ensuring initial conditions are incorporated.
For an undamped spring-mass system with a loading force F(t) = 10sin(ωt), derive the expression for the modal response q(t) using the Laplace Transform.
💡 Hint: Remember to handle 's' carefully and recall the properties of inverse transforms.
