A vibration isolation pad is designed for a machine operating at 60Hz. Calculate the expected magnitude of force transmitted if the damping ratio is 0.1 and the stiffness is 5000 N/m. Assume mass is 50 kg. (use H(ω) = 1/(k - mω² + icω))
💡 Hint: Ensure to consider how each variable influences the response.
Discuss how you might modify a system to enhance its damping and reduce significant resonance effects observed at certain frequencies.
💡 Hint: Focus on how damping affects the overall system stability.
