Abstract
THIS paper includes a somewhat critical review of formulas and methods for determining the beam strength of gears now being used.
The authors describe what they consider to be a new, more accurate approach to this problem. It is based on photoelastic work, combining the best features of two existing methods. Some data from actual gear test runs are shown verifying the accuracy of the new solution.
