Abstract
A method for measuring the axial force exerted on a body to be measured by applying two ultrasonic frequencies respectively having a transverse-wave vibration mode and a longitudinal-wave vibration mode to a body on which an axial force is exerted, measuring the natural frequencies of the body in the transverse-wave and longitudinal-wave vibration modes, obtaining the result of a computational operation (e.g., the result of a subtraction) on the measured natural frequencies, and measuring from this result the axial force exerted on the body in accordance with the predetermined result-versus-axial force calibration values.
