Question:
The two degree-of-freedom damped and forced system of Figure 6.78 oscillates about its equilibrium position. Use Lagrange's equation to formulate the problem and then solve the equations of motion for \(F(t)=A \cos \omega t\). Check whether proportional damping is a valid model here. If not, how can the system be modified so that such a model is valid? Make this modification, and then solve via modal analysis.
