A structure experiences free vibrations after being disturbed. If its mass is doubled, how does this affect its natural frequency?
💡 Hint: Refer to the relationship expressed in the natural frequency formula.
For a damped system with a damping ratio of 0.5, describe the expected motion behavior compared to critically damped systems.
💡 Hint: Consider how oscillations behave differently based on energy dissipation.
