Question:

For the system shown in Figure 6.13, solve for the responses where $k_{1}=k_{2}=k_{3}=k, m_{1}=m_{2}=$ $m$, and where the initial conditions are $x_{1}(0)=$ $1, x_{2}(0)=1$, and zero initial velocities, all in appropriate units. Plot the modes, identifying the nodes. Plot $\omega_{1,2}$ vs. $m$ and $k$.
