9.11 Figure P9.11 shows a 1-DOF mechanical system driven by the displacement of the left end, (), which could be supplied by a rotating cam and follower (see Problem 2.2).

When displacements X() = 0 and r = 0 the spring k is neither compressed nor stretched. The system purameters are Im = 2 kg. k = 50K) N/m,and h = 20N-s/m. Determine the frequency response if the position input is x(1) = 0.04 sin 50r m.
