An investigation was conducted to develop methods and equipment for the measurement of operating stresses in aircraft-engine crankshafts and connecting rods. Ranges of alternating stress were measured under motoring and power conditions at several locations on the master connecting rod and at one location on the crankshaft of a nine-cylinder radial air-cooled engine modified for test purposes. The results indicate that the measurement of stresses in connecting rods is feasible. Some resonant bending vibration occurred in the rod under all engine operating conditions investigated, but no appreciable resonant axial vibration was found.
