Analysis



Questions

Please answer the questions below.

In your own words, what is resonance?  Provide an example from everyday life.


Specifically for the mass-spring system in this computer experiment, what does resonance mean?


Take a series of screen shots showing ‘in phase’ resonance between the mass-spring and the driver. (Upload them here)

Take a series of screen shots showing ‘out of phase’ resonance between the mass-spring and the driver. (Upload them here)

Provide three sets of conditions where you found resonance between the mass-spring and the driver.  For each example, state whether the mass-spring was in phase or out of phase with the driver.


Summarize the cause-effect relationship between the mass-spring system and each parameter, in terms of what effect each parameter has on the vibration of the mass-spring system.  Include observations of both transient and steady-state behavior.  Which parameters are most important to find resonance between the driver and the mass-spring system? 

Think of this as you are helping a student who doesn’t have access to this simulation. Write what you would tell them what you learned in your use of the simulation including illustrations that could be helpful.
