$1$a$.$ For the geometry shown below, use the stress concentration tables to determine the stress concentration factor for the fillet. $($Note that these last four questions all have the same geometry and loading.$)$

$1$b$.$ For the geometry shown below, use the stress concentration tables to determine the stress concentration factor for the hole. $($Note that these last four questions all have the same geometry and loading.$)$

$1$c$.$ A load of $2$kip is applied to the member shown below. What is the maximum stress in kips$//$in$^(2)$ experienced by the member? $($Note that these last four questions all have the same geometry and loading.$)$
