<p>The device has a pre-stressed cord (9) arranged in a hollow section (7) e.g. carrier structure. The cord and/or the hollow section are arranged in an arc-shaped manner. The cord is fastened at two points in the hollow section and/or in an area of a connection point of the hollow section in an adjacent component, where the points are arranged at a distance from each other. The cord is fastened in such a manner that the pre-stressing produced by the cord acts on the hollow section against a force effect, which is to be estimated, at the hollow section.</p> |
