1. The problem statement, all variables and given/known data The right triangles of the plane truss are all the same. What are the forces in members BH and HG? Diagram for question is below, or a link: http://puu.sh/nsw1k/aad8a8b134.png [Broken] 2. Relevant equations n/a 3. The attempt at a solution Reaction force at A + reaction force at E are equal, therefore both = 15kN. It was after this point I became stuck. I calculated the forces in the x axis: ABcos60 + AHcos30 = 0 Then in the y axis: ABcos30 + AHcos30 = 15kN Not sure if the above is correct, and not sure how to continue with the question. Any help would be great!!!
