A deformation responsive weighing apparatus for measuring loads applied thereto comprises a straight, longitudinal bar of uniform circular cross section which is elastically deformable in response to loading, the bar being retained by bar supporting members adjacent the ends of the bar. A load applying member is located on the bar between the bar supporting members, the bar supporting members cooperating with the load applying member to elastically deform the bar from a straight condition as a load is applied to the bar. Each supporting member includes a bar mounting socket to receive an end of the bar, and a pin aperture in each socket is arranged in registering relationship with pin bores at the ends of the bar to form passages through bar and socket which are generally perpendicular to a plane defined by the central axis of the bar and the load vector. Pins extend through the pin apertures and pin bores at the ends of the bar to retain the bar in the sockets. Strain gauges are mounted on the bar to measure the deformation of the bar, and measuring circuitry detects the changes in electrical properties of the strain gauges caused by loading to provide a measurable response indicating the magnitude of the load.
