- 12 A Circular Cylindrical Rod With A Uniform Cross Sectional Area Of 20 Cm Is Subjected To A Mean Axial Force Of 120 K 1 (63.29 KiB) Viewed 38 times
12. A circular cylindrical rod with a uniform cross sectional area of 20 cm² is subjected to a mean axial force of 120 kN. The fatigue strength of the material is 250 MPa after 106 cycles of fully reversed loading and ou 500 MPa. Estimate the allowable amplitude of stress using Goodman, Gerber and Soderberg predictions for which the shaft should be designed to withstand at least one million fatigue cycles. Take Oy = 0.7 Qu. State all your assumptions clearly. Ans: 220 MPa, 246.4 MPa, 207.1 MPa
