  • CONTACT PROBLEMS AND STRESS DISTRIBUTION OF A

    (4) In design practice, the pin is designed to bear contact pressure (bearing stress) and bending moment, assuming the angle of contact area and the pressure distribution. In many designs, the contact angle is set at 90 degrees and pressure is a cosine distribution4). These assumptions must be verified. 3.
