  • Shoulder-Fillet Stress Calculations Clarified
    Procedures for calculating shoulder-fillet stresses should take multiaxial stresses into account, even if loading is uniaxial. * Shoulder fillets are notches that generate transverse stresses under axial loading. * Von Mises equivalent stresses let engineers determine the maximum principle stress
  • Bearing Mounting
    For instrument bearings, certain special considerations should be emphasized: Accurate axial positioning of the shaft relative to the housing requires shoulders, snap rings, or bearing flanges. Diameter of a shaft or housing shoulder must be sufficient to ensure solid seating and support
  • The Application of OIM to Friction Stir Processing of Cast NiAl Bronze Materials (.pdf)
    Institute for high-strength aluminum alloys [1-3]. In FSP, a cylindrical, wear-resistant tool consisting of a smaller diameter pin with a concentric, larger diameter shoulder is rotated and forced into the surface of a work piece. As the tool penetrates, a combination of frictional and adiabatic
  • Understanding Microscopes
    , while the Japanese Standard (JIS) is less commonly used. DIN microscopes begin with an object-to-image distance of 195mm, and then fix the object distance (with respect to the rear shoulder of the objective) at 45mm. The remaining 150mm distance to the eyepiece field lens sets the internal real image
  • Bearing Loads
    or severe instantaneous loads on rotating bearings. for instrument bearings is defined as the load causing a permanent, plastic deformation of 0.001 in. of the ball diameter at the ball-raceway contact. This deformation degrades the smoothness and noise level of the bearing. However, in less critical
