Part B

As shown, an L$-$shaped bar is supported by a pin at joint $A.$ The bar's dimensions are $a=610mm$ and $b=400mm,$ and the bar is subjected to a force with magnitude $F=5\mathrm{.}65$ kN at joint $B.$ Ignoring the bar's weight, find the actual orientation of the applied force. What is the value of the angle $?$
