3. (20 points) The system shown in Figure 3 has m=10kg,b=100Ns/m, and k=1440N/m. A ground motion p(t)=10sin24t(mm) is applied to the system. Determine the steady state motion of the mass m. gure 3 (20 points) For the same system of the Problem 3, the value of b is to be reselected such that the steady state magnitude of the mass movement is 4mm or less (no change in the values of m and k ). 3.
