A rectangular bar is cut from an AISI $1020$ cold$-$drawn steel flat. The bar is $2\mathrm{.}000$ in wide by $\backslash (5/8\backslash )$ in thick and has a $0\mathrm{.}400-$in$-$dia. hole drilled through the center as depicted in Table A$-15-1.$ The bar is concentrically loaded in push$-$pull fatigue by axial forces $\backslash ($ F$\_\{$a$\}\backslash ),$ uniformly distributed across the width. Using a design factor of $\backslash ($ n$\_\{$d$\}=2\backslash ),$ estimate the largest force $\backslash ($ F$\_\{$a$\}\backslash )$ that can be applied ignoring column action.

What are the values of the theoretical stress$-$concentration factor, the notch sensitivity$,$ and the fatigue stress$-$concentration factor?

The value of the theoretical stress$-$concentration factor is

The value of the notch sensitivity is $.($Round the final answer to three decimal places.$)$

The value of the fatigue stress$-$concentration factor is $.($Round the final answer to three decimal places.$)$
