Definitions

  • FIG. 7 there are shown, along one of the two arcs of contact profile, arrows representing the forces or stresses which are developed by the deformation shown in FIG. 6 in such a manner as to avoid excessive stress in the direction of the major axis of the head cross-section, and which thus avoids possible failure in the direction of the minor axis of the elliptical cross-section.
