A solid square rod is cantilevered at one end. The rod is 0.600 m long and supports a completely reversing transverse load at the other end of ±1.70 kN. The material is AISI 1080 hot-rolled steel. If the rod must support this load for 5.000 × 104 cycles with a design factor of 1.5, what dimension should the square cross section have? Neglect any stress concentrations at the support end. Determine the endurance limit for this application. Assume that the size modification factor %media.formula1960.mml% is 0.85 until a size for the section is known. The endurance limit is 168.0 MPa.

Two steels are being considered for the manufacture of as-forged connecting rods subjected to bending loads. One is AISI 4340 Cr-Mo-Ni steel capable of being heat- treated to a tensile strength of 260 kpsi. The other is a plain carbon steel AISI 1040 with an attainable Sut of 113 kpsi. Each rod is to have a size giving an equivalent diameter de of 0.24 in. Determine the endurance limit for each material. Is there any advantage of using the alloy steel for this fatigue application?

Problem 4: A cast iron shaft, ASTM-25 with an ultimate tensile strength of 25,000 psi, is subjected to a tor- sional load which is completely reversed. The load is to be applied an indefinite number of cycles. The shaft is 2" in diameter and is joined to a 3" diameter shaft with a " radius fillet. The factor of safety is to be 2. What is the maximum torque that can be applied to the shaft? Solve by two methods: (1) using Soderberg's equation, (2) using s = Tc/J directly.
A steel rod is subjected to a reversed axial load of 180 kN. Find the diameter of the rod for a factor of safety of 2. Neglect column action. The material has an ultimate tensile strength of 1070 MPa and yield strength of 910 MPa. The endurance limit in reversed bending may be assumed to be one-half of the ultimate tensile strength. Other correction factors may be taken as follows: For axial loading (Ka) = 0.7; For machined surface (Ksur) = 0.8 ; For size (Ksz) = 0.85 ; For stress concentration(Kf)= 1.0.3.
