A stationary circular section shaft has journal bearings $($simple supports$)$ at $x=0\mathrm{.}4($section $B)$ and $x=1\mathrm{.}4($section G$).$ The bearing at G provides axial support for the shaft. The shaft carries a variety of transverse forces, axial forces, and axial torques. $($a$)$ Sketch internal load diagrams $($transverse shear force $V(x),$ bending moment $M(x),$ axial torque $T(x),$ and axial force $F(x))$ for the bar.

$($b$)$ Five potential critical points P$1-$P$5$ are indicated on the shaft. Using your internal load diagrams and the stress elements provided, indicate the stress components $($bending normal stress, ${}_m,$ axial normal stress, ${}_A,$ transverse shear stress, $v,$ torsional shear stress, ${}_T)$ acting at the points. Show the proper directions for the stress components, but do not calculate numerical values. Do not show a stress component if its value is zero. P$1$ and P$2$ are on the top or bottom fibers of the bar. P$3$ and P$4,$ and P$5$ are at the neutral axis. Point P$5$ is on the "hidden" side of the bar.
