Question: Calculate the natural frequencies of the hydraulic system sketched in Figure. Is it possible that the amplitudes of the flow rates in the two meshes are equal during either of the two modal motions and the directions of these flows are identical (i.e., either clockwise or counterclockwise)?
Known are: Cn = 1.8 x 10-6 m5/N, C12 = 2.2 x 10-6 m5/N, Il = 3 x 104 N-s2/m5.
