STABILITY OF ACOUSTIC EXTENSOMETERS DESIGNED TO MEASURE THE THRUST IN A SHIP'S PROPELLER SHAFT

The paper considers the problems involved in using acoustic (vibrating wire) strain gages to measure the compressive strain associated with the thrust in a ship's propeller shaft. The paper reports the results of a series of measurements of the stability of the new gages. These measurements were made under field conditions, i.e. with the gages installed on the propeller shafts of ships in normal service. It is shown that strain gages of suitable design permit measuring the extremely small compressive strain due to the thrust of a ship's propeller on its shaft.
