For my school project, I am trying to measure the effect of a mass damper by changing the length of the string (that carries the mass), my setup is similar to the following video: https://youtu.be/f1U4SAgy60c?t=4m4s
I am trying to find a relationship between the length of the string and the oscillation of the "building". But I don't know exactly what the guy in the video is trying to measure and if it is related to what I'm trying to do.
Is it possible to use an accelerometer to map the oscillation of the "building" and if so, is there a relationship between the accelerometer data and the displacement of the oscillation?
My aim is to find the maximum amplitude for different lengths of string, so does a larger amplitude from the accelerometer data correspond to a larger amplitude in the displacement time graph?
I am desperate for help as I would much rather use accelerometer data rather than use a ruler in the background to measure the displacement of the oscillation.
Thank you in advance!!!
