Required information A solid square rod is cantilevered at one end. The rod is 0.7 m long and supports a completely reversing transverse load at the other end of ±1.8 kN. The material is AISI 1080 hot-rolled steel. If the rod must support this load for 5.5 × 105 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...
