Extracted text: Problem 1.2-9. A truss carries two forces: a 50 kN is acting perpendicular to AB, and a 70 kN is vertically downward. A pin supports the truss at A and a roller at H. The truss members' cross-sectional areas are 600 mm2 for the top cherds (AB, BD, DF, and FH), 700 mm2 for the bottom chords (AC, CE, EG, and GH), and 500 mm2 for the other members.
