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