Between a solid mass of 1P kg and floor, two slab of isolator, natural rubber and felt are kept in series as shown in Figure Q1(b). The natural rubber slab has a stiffness of 3Q00 N/m and an equivalent viscous damping coefficient of 11R Ns/m. The felt slab has a stiffness of 12,800 N/m and an equivalent viscous damping coefficient of 1T0 Ns/m. (i) Sketch the single degree of freedom spring-mass-damper system (2 marks) (ii) Determine the undamped and damped natural frequencies of the system in the vertical direction. Neglect the mass of the isolator
