$3.$ Determine the horizontal and vertical components reaction forces at pins A and $C$ by:

$(22$ pts total$)$

a$)$ drawing appropriate free body diagram$($s$)$ of the machine

$(7$ pts$)$

b$)$ solving multiple sets of equations of equilibrium.

$(15$ pts$)$

Assume: $a=0\mathrm{.}8m,b=0\mathrm{.}9m,c=0\mathrm{.}5m,d=0\mathrm{.}4m,e=1\mathrm{.}2m,F=500N,=45$ Note: simplify your analysis by using the unique properties of member $BC$
