ABSTRACT:
An apparatus for measuring forces across a flexible member is provided comprising a non-extensible element suspended between a pair of supports. The non-extensible element is operably coupled to a flexible member for translating forces applied to the non-extensible element to the flexible member. A pair of equally massed weight dishes are suspended from said non-extensible element on opposite sides of the flexible member. By incrementally adding weights to one of the weight dishes, the flexible member is incrementally displaced. An Eddy Current System operably communicates with the flexible member for detecting the displacement. The displacement and load are used to calibrate a stress-strain curve of the flexible member.
