The lunar excursion module has been modeled as a mass supported by four symmetrically located legs, each of which can be approximated as a spring-damper system with negligible mass (see Fig. 2.121). Design the springs and dampers of the system in order to have the damped period of vibration between 1 s and 2 s.
