1. The problem statement, all variables and given/known data The diagram is attached. I must solve using method of sections the force in member HG. 2. Relevant equations ƩF(y) = 0, ƩF(x) = 0, ƩM = 0 3. The attempt at a solution My hand-drawn pic shows the section. Solving vertically, ƩF(y) = 0 F(DG)cos45 = 10 F(DG) = 14.1kN Moments about E 10(2) + 2F(DG)cos45 + 2F(HG) = 0 Dividing by 2 and rearranging: F(HG) = -10 - 14.1cos45 = -20kN I don't think I'd have a problem if there wasn't a pulley system and I can only assume the reason I'm not getting the correct answer for F(HG) is because I'm not taking into account the effect the pulley has. Can anyone advise a nudge in the right direct... ?
