1. A load-measuring device comprising a ring-shaped body,at least three circumferentially-spaced first axial projections presenting sectorially-aligned surfaces operatively mounted so that said surfaces engage a first of the two axial faces of said ring-shaped body;

  • at least three circumferentially-spaced second axial projections presenting sectorially-aligned surfaces operatively mounted so that said surfaces engage the second and opposite of said axial faces of said ring-shaped body at locations staggered relative to those of said first axial projection;

    means to detect the strain imposed upon said ring-shaped body when said ring-shaped body is distorted elastically to sectorially-undulating shape by opposed axial loads applied to said ring-shaped body through said first and second axial projections.
