Question 9 Consider again the mechanical system of Fig 8. Assume the parameter values m = 1 kg, b = 2 Ns/m, and k = 5 N/m. For time t 20, a force of 3 N is applied. (a) Assuming zero initial conditions, apply Laplace transform method to obtain an expression for the displacement x(t) for all t2 0. 3 3 3 Ans: X(t) = get cos 2t - - etsin 2t x (b) Sketch the approximate response curve, indicating clearly the initial conditions and the steady-state value. 55 10
