This is a question of one of the practice problems for this topic. After obtaining the forces in Joint A, I have no idea what the next step is as there are too many unknown forces. I would greatly appreciate the response. Determine the force in member BC (in kN, round-off to 2 decimal places, include "-" if in compression) of the truss.
