1. The problem statement, all variables and given/known data 2. Relevant equations ƩF_y=0 ƩF_x=0 ƩM=0 3. The attempt at a solution The weight of the wire is 500*16=8000lb I isolated each part of the system: Using a force triangle on the cross section of the wire, knowing it is a 345 triangle: 8000/4=B/3=D/5 B=6 kips D=10 kips I wrote equations for members ABC and CDE: for ABC: ƩMA = 6*d1 + 9*Cx = 0 for CDE: ƩME = 10*d2 - 6*Cx + 8*Cy = 0 d1 and d2 are the vertical distance from A to B, and the diagonal distance from D to E, respectively. This is what I had trouble finding. I tried using similar triangles: 5/8 = a/10 = (3+b)/6 b=0.75ft d2=6.25ft Since b is 0.75, d1 = 9 - 6 + 1.5 + 0.75 = 5.25ft Plugging these into the above equations, I get Cx = 3.5kips, and Cy = 10.4 kips, which are not the right answers.
