Required information

The upside$-$down steel A frame shown in the figure is to be bolted to steel beams on the ceiling of a machine room using ISO grade $8\mathrm{.}8$ bolts. This frame is to support the $\backslash ($ W$=53\backslash$mathrm$\{$kN$\}\backslash )$ vertical load as illustrated. The total bolt grip is $\backslash ($ l$=55\mathrm{.}0\backslash$mathrm$\{$~mm$\}\backslash ),$ which includes the thickness of the steel beam, the A$-$frame feet, and the steel washers used. The bolts are of size M $\backslash (20\backslash$times $2\mathrm{.}5\backslash ).$ Determine the factors of safety guarding against yielding, overload, and joint separation. $($Round the final answers to three decimal places.$)$

The static factor of safety, $\backslash ($ C $\backslash ),$ is

The yielding factor of safety, $\backslash ($ n$\_\{$p$\}\backslash ),$ is

The overload factor of safety, $\backslash ($ n$\_\{$L$\}\backslash ),$ is

The separation factor of safety, $\backslash ($ n$\_\{$O$\}\backslash ),$ is
