Q$1.$

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 distortionenergy 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 $T=25N*m.$
