Question about Damped Simple Harmonic Oscillation ?

Click For Summary
SUMMARY

In damped simple harmonic oscillation, amplitude resonance and velocity resonance occur at different frequencies due to the nature of the damping effect on the system. As the driving frequency increases, the amplitude reaches its maximum at a specific frequency where the slope of the amplitude function is zero. However, the velocity continues to increase with frequency, resulting in a maximum velocity that occurs at a slightly higher frequency than the maximum amplitude. This distinction is crucial for understanding the dynamics of damped oscillatory systems.

Question about Damped Simple Harmonic Oscillation !?

Under appreciable damping , Why amplitude resonance and Velocity resonance occurs at slightly different frequencies ?

Say we have a damped system driven at some frequency. The amplitude will be some smooth function of frequency. At max amplitude the slope of the function will be zero. Increase the function slightly, the amplitude does not change (much) but because the frequency is greater the velocity will be greater. The maximum will occur at different frequencies.

Does that seem to make sense? %^)
