Use Figure 10.2 shows a multi-degree-of-freedom (MDOF) model of three connected masses. Find the following for the MDOF system in Figure 10.2: i. Find expressions for the kinetic energy (T) and potential energy (U) using the provided parameters (x1,x2,x3,k1,k3,m1,m2, and m3). ii. Using Lagrange's equations, derive the EOMs in matrix form.
