Two external forces are applied to a structural member $\backslash ($ A B C $\backslash )$ as shown in the figure

a$.)$ Draw a free$-$body$-$diagram $($FBD$)$ of ABC when

$\backslash [$

$\backslash$theta$=0^\{\backslash$circ$\}$

$\backslash ]$

b$.)$ Use appropriate equations of equilibrium and the above FBD to determine the reaction force at A

c$.)$ Use appropriate equation of equilibrium to find the reaction and direction of force at C d$.)$ Now redraw free$-$body$-$diagram $($FBD$)$ of ABC when $\backslash (\backslash$theta$=30^\{\backslash$circ$\}\backslash )$

e$.)$ Use appropriate equations of equilibrium and the FBD in d$.)$ above, to determine the reaction force at A

f$.)$ Use appropriate equation of equilibrium to find the reaction and direction of force at C
