A Single-Plane Rotating Imbalance Experiment

Abstract

A simple experiment to demonstrate single-plane rotating imbalance is described. Inexpensive and commonly available items were used in the experiment to emphasize the concepts presented in an uncluttered manner and to underline the importance of simplicity. Students were also required to assemble the experiment by themselves to maximize experiental learning. The experiment was able to provide accurate predictions of the angular position and magnitude that an imbalance mass imposed.
