Rotational Motion - Lab Report ExampleThe mass and dimensions of the steel block were measured together with the errors receivable to measurement. The Data studio (DS) data acquisition program was opened and a file Desktop-pirtlabs-PHY 122-Rotational motion. The file was preset to record (t) and (t).Part I The block was wedded through its shortest axis onto the rotary encoder. The string was put on the medium pulley and wind it up entirely in a direction so it will unwind CCW (counterclockwise) when facing the pulley. The readings were taken.Therefore, the dynamic moment of inertia along the short axis is greater than one for the long axis. However, the theoretically calculated motionless moment of inertia lies within the range defined by the dynamic moments of inertia calculated practically. It is, however, important to notice that the dynamic moments of inertia obtained are of the said(prenominal) order with Id for medium pulley through short axis (Id = 1.66 * 10-4) being sli ghtly higher for the long axis (Id = 1.52 * 10-4). The moments of inertia obtained are affected by the distribution of mass from the center of mass of the object used. Thus, accurate and precise measurement of parameters that determine the moment of inertia can produce results that are close-fitting to the absolute results predicted through a theoretical approach.
