Consider the mechanical system shown in the figure. The system is initially at rest. The displacements x1 and x2 are measured from their respective equilibrium positions before the input u is applied. Assume that b1=1Ns/m, b2=10Ns/m, k1=4N/m, and k2=20N/m. Obtain the displacement x2(t) when u is a step force input of 2 N. Derive the transfer function and then plot the response for a ramp input u(t)=2t N. a) Plot the response for 5s using lsim command. b) Plot the reponse for 5s using impulse command. c) Plot the response for 5s using step command.
