Question

6-13 A solid square rod is cantilevered at one end. The rod is 0.6 m long and supports a completely reversing transverse load at the other end of ±2 kN. The material is AISI 1080 hot-rolled steel If the rod must support this load for 101 cycles with a design factor of 1.5, what dimension should the square cross section have? Neglect any stress concentrations at the support end
