The figure below shows a rectangular section aluminum bar subjected to off$-$center forces P

$=4000$ N

applied as shown. All dimensions in the figure are in mm

$.$

A vertical bar has a thickness of $10$ units and a width of $40$ units. Opposite vertical forces P are applied through eyes on the top and bottom of the bar. The forces are directed away from the bar. Both eyes are fastened to the bar at $35$ units from its left edge.

Part A

Part complete

Solve for the maximum normal stress in the mid$-$region of the bar well away from the eyes where the loads are applied.

Express your answer to three significant figures and include the appropriate units.

$\backslash$sigma max

$=$

$32\mathrm{.}5$ MPa

Correct

Part B

Plot the normal stress distribution across the cross section at this mid$-$region of the bar. Here, y

is the distance from the neutral axis.
