Consider a typical unbalanced machine problem as given in the figure below, with a machine of total mass of m= 100 kg (including the out-of-balance mass), a mount stiffness of k = 5 MN/m and a damping value of c = 26876 kg/s. The out-of-balance mass is measured to be mo = 5 kg at a running speed of w = 3600 rpm. Determine the steady state amplitude of motion due to the out of balance mass. Assume eccentricity e 200 mm.

Consider a typical unbalanced machine problem given in the figure below, with a machine of total mass of m= 100 kg (including the out-of-balance mass ), a mount
stiffness of k = 5 MN/m and a damping value of c = 26876 kg/s. The out-of-balance mass is measured to be mo = 5 kg at a running speed of w = 3600 rpm. Determine
the steady state amplitude of motion due to the out of balance mass. Assume eccentricity e = 200 mm.
