Problem $5-36$

This problem illustrates that the factor of safety for a machine element depends on the particular

point selected for analysis. Here you are to compute factors of safety, based upon the distortion$-$

energy theory, for stress elements at A and $B$ of the member shown in the figure. This bar is made

of AISI $1006$ cold$-$drawn steel and is loaded by the forces $F=0\mathrm{.}55kN,P=4\mathrm{.}0kN,$ and $T=25$

$N*m.$

Answer: $n=4\mathrm{.}49$ at point $A$;$n=1\mathrm{.}4$ at point $B.$
