According to Goodman's criterion what is the safety coefficient for infinite life or the number of cycles for fatigue failure of the support set in the machine frame, as shown in the Figure, The device receives a varied load ranging from a minimum value of 100 lbf to a maximum of 1100 lbf. M frame beam F r-fillet K₂ = 1.5 max = 1 100 mean = 600 min = 100 d Data: - The completely corrected fatigue strength limit is Se=22 kpsi. - The material is SAE 1040 normalized steel with Sut = 80 kpsi and Sy = 60 kpsi Dimensions are b = 2 in; d = 1 in; D = 1.125 in; r=0.5 in; a = 5 in and 1 = 6.0 in.
