Problem $3\mathrm{.}92*$

Repeat Prob. $3-91$ with $F_x=0,F_y=175lbf,$ and $F_z=100lbf.$

Problem $3\mathrm{.}91*$

The cantilevered bar in the figure is made from a ductile material and is statically loaded with $F_y=200lbf$ and $F_x=F_z=0.$ Analyze the stress situation in rodAB by obtaining the following information.

$($a$)$ Determine the precise location of the critical stress element.

$($b$)$ Sketch the critical stress element and determine magnitudes and directions for all stresses acting on it$.($Transverse shear may only be neglected if you can justify this decision.$)$

$($c$)$ For the critical stress element, determine the principal stresses and the maximum shear stress.
