A mechanism for reducing horizontal force in a load measurement is presented. The mechanism includes a structure having surfaces of nonuniform radii of curvature (e.g. oblate spheroid surfaces) at both ends. The ends of the structure contact a force-sensor coupling element and a base-coupling element forming two interfaces. Each interface includes a contact area between a convex surface and a concave surface. When a horizontal force is applied the , contact area at each interface shifts allowing the structure to tip from the vertically aligned position that it is in when no horizontal force is applied. Compared to coventional mechanisms, the structure of the invention has a lower …
