    The machine shown in the figure is rigidly anchored on a rigid concrete block and the mass of both is 3000 kg. The block has height h = 1 m and square horizontal section with a = 1.2 m and is supported at the corners by 12 springs of stiffness k = 2000 N/m.

    Solve only the second part: (see attachment for diagram)
    ii) Find the natural frequencies and mode shapes of the system using both hand calculations and Matlab.
