$1\mathrm{.}7$ A flat bar of width $b=2in$ and thickness $t=0\mathrm{.}25in$ has a

hole of diameter $d=0\mathrm{.}5$ in drilled through it $($see figure$).$

What is the maximum repeated tensile load $P_{\text{m}\text{a}\text{x}}$ if the

bar is made with SAE $1080$ Annealed? $($Choose an

answer on Brightspace$).$

$1\mathrm{.}8$ From previous question $1\mathrm{.}7,$ a clevis pin goes through the hole and takes over the load $P$ on

one side.

The bearing stress ${}_b$ between the pin and the flat bar is

ksi if $P=10$kip? $($Answer

on Brightspace$).$
