Question: Method of Sections: Using the method of sections ( no other method is acceptable ) , determine the forces acting in members EC , EF

Method of Sections:
Using the method of sections (no other method is acceptable), determine the forces acting in members EC,EF, and BF of the truss shown below and indicate whether the member is in tension or compression.
Must show the following to receive full credit.
a. Free-body diagram of each section being analyzed.
b. Calculations.
Note: Assume support A is pinned and support D is a roller.
steps would be nice
