Question

The component shown below is made of AISI 4340 Oil Quenched at 800°C and Temper at 595oC 1 hour (@yield-139ksi; ơTS-147ksi) tubular steel. The component, a closed end tube with an OD-1.25in and ID 3/4in, is subjected to the load (see arrow) that varies between 3F and F. Determine the force F for infinite life. Given: The component has been cold rolled operates at room temperature and needs a reliability of 99.0%. Consider a Safety Factor of 1. Stress concentrators at the base for axial, bending, torsion and shear stresses are 1.6, 1.7, 1.4 and 1.2 respectively. 12 in. 4 in. I 5 in. ん 6 ini
