Abstract

Apparatus is provided for introducing a force to be measured from a force transfer element into the free end of a bending rod held rigidly at one end. The apparatus comprises means, e.g. two knife-edges for guiding the force transfer element in the direction of the bending rod, a first rounded contact surface on the force transfer element, a second rounded contact surface on the bending rod, a coupling element having first and second flat parallel spaced substantially horizontal surfaces and interposed between the first and second contact points with its first surface bearing against the first contact surface and its second surface bearing against the second contact surface, and means for holding the coupling element substantially centrally and resiliently relative to the first and second contact surfaces.
