A coil spring suspension is designed as a suspension for a mega truck that will be released in the future with a viscous damper. a.) What is the bumper's damping coefficient such that the system has a damping ratio of 1.25 when the bumper is engaged by a 20 tons railroad car and has a stiffness of 2 x 10^5 N/m? b.) Another load for the truck has been installed that has a mass of only 4500 kg. What are the natural frequency and a damping ratio of a system with the coil spring suspension when the load is being applied?
