Q$2.(2\mathrm{.}5$ pts$)$ The system is in equilibrium. Determine the components of the reactions at D and $E$ if the frame is loaded with a $300-N$ load at A$.[$Hint: Dismember and draw FBD for each member.$]$

a$)$ Draw FBD for the entire system and find determine reactions at $D$ and $E.$

b$)$ Draw FBD for each member $-$ACD,BCE.

c$)$ Determine forces on each member. Please show the directions clearly.
