A multi DOF vilestory system shown in Figure 4 is composed of severak mas, spring and damping elements. 12047 x200+ II 0² H Ha Figure 4 Derive the equation of motion of the system by applying Lagrange equations b. Calculate the natural frequencies by applying "modal analysis c. Define and draw the mode shapes of free, undamped motion d. Leing the apt of Generalized Mas, vamine the orthogonality of the mobil vectors MATLAB Coding Write ale to e. Apply modal analysis to the mass and stiffness matrices. Do NOT use the built in fuation "gen values urgentes f. Using the modil vectors that you cakulated in (c), write a code to check the wagonality of the codes System parameters: k₁=-= k:=26519.2 N/m.₁m₁=450 kg. c₁==1000 Ns/mem HA T xla)
