Abstract:  
An improved method has been developed for choosing the sizes of power-transmitting shafts for limited or unlimited service lives under a variety of operating conditions. In essence, the method replaces some traditional simplifying approximations and guesswork by more-refined design equations based on considerations of metal fatigue. The method will be especially beneficial where critical compromises have to be made between shaft weights and reliabilities or where the penalties of shaft failure are severe.
