6-30 The figure shows the free-body diagram of a connecting-link portion having stress concentration at three sections. The dimensions are r = 0.25 in, d = 0.40 in, h = 0.50 in, W₁ = 3.50 in, and w₂ = 3.0 in. The forces F fluctuate between a tension of 5 kip and a compression of 16 kip. Neglect column action and find the least factor of safety if the material is cold-drawn AISI 1018 steel. F Problem 6-30 W₁ 6-31 A F W₂ →h Section A-A Solve Problem 6-30 except let w₁ = 2.5 in, w₂ = 1.5 in, and the force fluctuates between a tension of 16 kips and a compression of 4 kips. Use the Goodman criterion.

Need problem 6-27 solved not 6-25. You only need to use Goodman Fatigue Failure Theory. Please provide all work possible, steps, units and highlight the answer. Thanks!

6-33 The torsional coupling in the figure is composed of a curved beam of square cross section that is welded to an input shaft and output plate. A torque is applied to the shaft and cycles from zero to T. The cross section of the beam has dimensions of 16×6 in, and the centroidal axis of the beam describes a curve of the form r = 0.75 + 0.4375 0/л, where r and 0 are in inches and radians, respectively (0 ≤ 0 ≤ 4л). The curved beam has a machined surface with yield and ultimate strength values of 60 and 110 kpsi, respectively. (a) Determine the maximum allowable value of T such that the coupling will have an infinite life with a factor of safety, n = 3, using the Goodman criterion. (b) Repeat part (a) using the Morrow criterion. (c) Using T found in part (b), determine the factor of safety guarding against yield.
