Abstract
The author points out that the analysis of the flywheel problem most commonly used is based upon the assumption that the shafting connecting the various masses is infinitely rigid, and that there is no agreement on whether or not the engine, flywheel, and generator mass are to be accounted for, the usual opinion being that the flywheel and engine only enter into the result. Attention is called to the fact that the inherent errors of the ordinary solution have been exposed by several authors, but that no specific attempt has been made to compare quantitatively the results obtained by the correct solution with those as ordinarily calculated. The author discusses both solutions of the problem, and compares results obtained with torsiographic data taken on actual installations.
