A system has the following dynamics equations 3 0 LO 10-62218- ] o||2+ + 1) L83 3 4 -2 -1 -21X1 [fi(t)] -1||X2= |f2(t) 3 X3 |fz(t)] M K (a) Calculate the natural frequencies (eigenvalues) of this system. (b) Calculate the mode shapes (eigenvectors) of this system in the following format (let y(i) = 1); = X(1) X(2) -0% ? x(3) = = ? (c) Check orthogonality. Are the above eigenvectors orthogonal over the matrices M and K? Show your calculation.
