ABSTRACT:
The present invention is intended to provide a stress detecting and measuring method wherein in order to measure a shearing strain alone associated with a stress acting in an intended direction, the stress being one of the stresses acting on an axle of a vehicle or a structure having a fixed support point adjacent the axle, the conditions for the optimum position where a stress sensor is to be mounted are indicated. Further, the invention is intended to provide a stress detecting device which accurately measures a shearing strain alone associated with a stress acting in an intended direction by further separating a plurality of stresses acting on a stress sensor. For example, in the case where stresses are applied in two directions to a structure having a fixed support point, in order to measure a shearing strain alone associated with a stress acting in an intended direction, a stress sensor should be mounted in a position which is a transformation knot zone for the other stress strain, i.e., a zone where shearing stress strain is minimum, and which is suitable for measurement of the intended stress.
