An AISI 4142 steel Q&T at 800F exhibits Syt 5
Chapter 5, Problem 5-14(choose chapter or problem)
An AISI 4142 steel Q&T at \(800^{\circ} \mathrm{F}\) exhibits \(S_{y t}=235 \mathrm{kpsi}, S_{y c}=285 \mathrm{kpsi}\), and \(\varepsilon_f=0.07\). For 5-18 the given state of plane stress, (a) determine the factor of safety, (b) plot the failure locus and the load line, and estimate the factor of safety by graphical measurement.
