For use in weighing devices of the kind employing strain measurement in a bending beam, a force transmission element comprises a rectangular prismatic body of elastomeric material such as natural rubber having waisted sides (15). Fixing studs (17) are attached by means of plates (16) bonded to the upper and lower surfaces of the body. The material of the body is chosen to exhibit characteristics of creep, hysteresis and linearity approximating those of an ideal spring. A weighing device in which a distributed load is measured with the use of a single bending beam is also described.
