A harmonic force of F(t) = Fo cos(wt) is applied to the system shown in the following figure. With zero initial velocity and initial displacement, the response is observed to be x(t)= 6 sin(0.4t) sin(3.7t). Based on the following information, determine the ratio of the excitation frequency to the natural frequency of the system (w/wn). ‒‒‒‒‒‒‒‒‒‒‒ E₁, A₁, L₁ m Fo cos wt E2, A2, L2
