Using the MATLAB function ode23, find and plot the forced-vibration response of the system described in Problem 6.89.

Data From Problem 6.89:-

Determine the amplitudes of motion of the three masses in Fig. 6.40 when a harmonic force \(F(t)=F_{0} \sin \omega t\) is applied to the lower left mass with \(m=1 \mathrm{~kg}, k=1000 \mathrm{~N} / \mathrm{m}, F_{0}=5 \mathrm{~N}\), and \(\omega=10 \mathrm{rad} / \mathrm{s}\) using the mode superposition method.
