This article summarizes our calculation of the normal modes and the normal coordinates for a commercially available Wilberforce pendulum. A procedure is presented by which the normal coordinates may be produced experimentally, so that the frequencies of the normal modes can be obtained both theoretically and experimentally. Where possible, results have been compared with those from previous papers. Finally, PCbasicprograms have been written in which the behavior of the Wilberforce pendulum has been theoretically reproduced.
