ABSTRACT:
A method for determining the deflection and/or strain of an elongated member of a component is provided, in which a first point and a second point are assigned to the same side of an elongated member of the component, wherein the deflection and/or strain of the elongated member is determined by determining the distance between the second point and a third point, which is connected to the first point by an inflexible support, whereby the distance between the first point and the third point is considerably longer than the distance between the second point and the third point, and wherein the distance between the second point and the third point is determined in time steps and the frequency of the change of the distance is analyzed to detect frequency changes. Furthermore, an elongated member of a component subject to strain and comprises a sensor unit for determining the deflection and/or strain of the elongated member.
