Can someone help me solve this problem? I Don't know how to start this. thank you

1. Determine the force in each member (example of notation: FBC indicates force in member BC) of the truss shown below USING ONLY THE METHOD OF JOINTS. Next to each force value, indicate if that member is in tension (write letter T in parentheses next to the value) or compression (write letter C in parentheses). You must provide an appropriately labeled free body diagram for each joint you use that shows all known and unknown forces acting on that joint. You are only required to evaluate enough joints to find all of the unknown member forces. You do not have to evaluate them in the order that they're labelled.
