Using MATLAB, find and plot the free-vibration response of the system described in Problem 6.79 for the following data: \(x_{20}=0.5, P=100, l=5, m=2\).

Data From Problem 6.79:-

Find the free-vibration response of the tightly stretched string shown in Fig. 6.33 for \(m_{1}=2 m, m_{2}=m, m_{3}=3 m\), and \(l_{i}=l(i=1,2,3,4)\). Assume the initial conditions as \(x_{1}(0)=x_{3}(0)=0, x_{2}(0)=x_{20}, \dot{x}_{i}(0)=0(i=1,2,3)\).
