I Figure P9.11 shows a 1-DOF mechanical system driven by the displacement of the left end, x,(t), which.could be supplied by a rotating cam and follower (see Problem 2.2). When displacements r() = 0 and x = 0 the spring k is neither compressed nor stretched. The system parameters are m = 2 kg, k = 500 N/m,and b = 20 N-s/m. Determine the frequency response if the position input is x,() 0.04 sin 50f m.
