Problem $06\mathrm{.}026-$ The cold$-$drawn AISI $1040$ steel bar

The cold$-$drawn AISI $1040$ steel bar shown in the figure is subjected to an axial load that fluctuates from $111436$ kN to $26$ kN $.$ Use the modified Goodman, Gerber, and Morrow criteria and compare their predictions. Estimate the fatigue factor of safety based on achieving infinite life and the yielding factor of safety.

Problem $06\mathrm{.}026.$a $-$ Determine the factor of safety against yielding

What is the factor of safety against yielding? $($Round the final answer to three decimal places.$)$

The factor of safety against yielding is
