9-3 翼応力の計測法について  [in Japanese] 9-3 Technique for the Measurement of the Stress of Model Propeller Blades  [in Japanese]

There are various problems in experimental technique concerning the measurement of stress of model propeller blades. This report shows solutions for these problems and a system of measurement established. According to this system, stresses of model propeller blades working behind a model ship were measured. The results of measurements show the effectiveness of this system.
