For the truss given below, determine:

a$)$ Force in members DF$,$ DB$,$ DC$,$ and DE using method of the joints.

b$)$ Force in members $BC$ and $AC$ using method of the sections

Clearly state if the members are in tension or compression in a$)$ and b$).$

$($Hint: Find the reactions at A and $F$ before using method of joint and section, and start $a)$ at joint $F)$
