A part of a racket in a machine assembly is shown in the Figure below. The load varies from 3.2 kN to 0.7 kN. The bracket is made from SAE 1050 hot-rolled steel. The actual endurance strength of the material is 124 MPa, and the stress concentration factor is 1.2. Determine the followings: The maximum stress The minimum stress The mean stress The alternating stress (MPa) 300 mm (MPa) (MPa) The resulting design factor (N) by using the Goodman method Load on bracket 600 mm (MPa) $35 mm A 6 m b = (0. +o ) max min 2 (o <-0 max My I 2 min A part of a racket in a machine assembly is shown in the Figure below.
