The part shown is loaded at point $C$ with $290\mathrm{.}0$ N in the positive $x$ direction and at point $E$ with $200\mathrm{.}0$ N in the positive direction. The diameter of the bar ABD is $1200$ mm $.$ Evaluate the likelihood of failure in section $AB.$

where $P=290\mathrm{.}0N,Q=200\mathrm{.}0N,$ and $d=12\mathrm{.}00mm$

For the critical stress element, determine the three principal stresses and the maximum shear stress.

The three principal stresses and the maximum shear stress are as follows:

${}_1=,$MPa

${}_2=,$MPa

${}_3=,$MPa $(Include$ a minus sign $if$ necessary.$)$

${}_{\text{m}\text{a}\text{x}}=,$MPa
