Extracted text: (b) A small generator of mass m is supported by four anti- vibration springs to reduce vibration levels being transmitted to the floor. Each spring has a stiffness of k N/m. Draw free body diagrams for: (i) The static equilibrium position for the system (ii) The dynamic case when the mass is displaced downwards by a deflection of x m and released. If the mass of the small generator m is 12 kg and (ii) each spring has a stiffness of 800 N/m and the vibration described as simple harmonic motion, calculate the frequency of vibration in Hz and time period of vibration.
