...T. J. Osler; E. Flores In a recent paper by Flores and Osler, the authors investigated tautochrone curves in the xy -plane under an arbitrary potential V y . In this paper we imagine that the xy -plane of the tautochrone curve is rotating about the y -axis with constant angular momentum. We find...

... approximate results are appropriate. Once these results are known, it is observed that a subsequent intuitive analysis based on time rate of change of angular momentum leads to the same results, if only the angular momentum about the spin axis is considered with other relevant assumptions.
