63 Figure P6.3 shows a mass-damper system (no stiffness, Problem 2.3). Displacement x is measured from an equilibrium position where the damper is at the "neutral" position. The external force () is a short-duration pulse function: f(!)-5N for 0SS002 s, and f,() = 0 for t > 0.02 s. The system parameters are mass m-0.5kg and viscous friction coefficient b 3 N-s/m and the system is initially at rest. Usc Simulink to determine the system response and plot displacement xit)...
1. A suspension system shown in the figure is modified by adding two additional springs each with a spring constant of k, kN/m in addition to the other existing three springs with k 90 kN/m each....
1. A suspension system shown in the figure is modified by adding two additional springs each with a spring constant of k, kN/m in addition to the other existing three springs with k 90 kN/m each. The design also adds two additional dampers in addition to the two existing dampers each with the same viscous damping coefficient c (= 4000 Ns/m). The viscous damping ratiofor the underdamped system, 7 is 0.95. The mass of the system, m = 150 kg....

A 1-kg mass is attached to a spring with stiffness 45N/m. The damping constant for the system is 6 N-sec/m. The mass is pulled 1 m to the right of the equilibrium position and released. Find the equation of motion in phase-shift form. When will the mass first return to its equilibriom position, and at what velocity?
