Hello all, I am currently working on a project where I am to analyze the rotation of a shaft in a particular piece of machinery and use this information to get a meaningful relationship between two other independent parameters of the machine. The rotation of the shaft is the only indicator that can be used to understand the evolution of this complex machine as it operates. I have measured this shaft rotation using a rotary encoder. I plotted angular velocity of shaft with its angular position. Now, if I were to integrate this relationship , i.e the area under the graph of this chart, what would that represent?
