• What is its effective length? (Note that the actual length of the beam material is 250mm).
• What are the five (5) fluids used as damping media?
• Calculate the logarithmic decrements of the beam in these five fluids.
• Calculate the damping ratio of these five fluids and rank them from the highest to the lowest.
• From experimental data, calculate the observed natural frequency of the basic beam system.
• Calculate the theoretical natural frequency of the system. How does this compare with the observed natural frequency?
