. The mass and stiffness matrices and the mode shapes of a two-degree-of-freedom system are given by ([m] = [] = [] [k] 12 -k12 -K12 k22 Xi₁ = [9.1109] X₂= [⁹] [-9.1109] If the first natural frequency is given by w₁ = 1.7, determine the stiffness coefficient K₁2 and K22 and the second natural frequency of vibration, w₂.
