ABSTRACT:
A strain gage load cell having a body of material formed with a reduced section which is subjected to shear stresses when a load is applied to the body in a manner to deform the reduced section, a strain gage receiving opening formed in the reduced section so that deformation of the latter will deform at least part of the opening and cause it to assume an ovular configuration and at least one strain gage secured to the wall of the deformable portion of the opening and preferably aligned with one of the axes of the deformed portion of the opening.
