1. The problem statement, all variables and given/known data http://home.exetel.com.au/peleus/EIDEprob.jpg 2. The attempt at a solution Basically did the standard sum of moments around point A to try and get the vertical component of point D. -6.2*997 + 9.2*Dy - 12.4*1472 Dy = 2655.89 From there working out Dx Dx = 2655.89 / tan 50 Dx = 2228.56 Then doing some Pythagoras finding CD to be 3467N. Supplied answer is 2476N. I think I'm going wrong for a few possible reasons, 1 - It's possible that the distances I'm using aren't perpendicular to the forces, I tried working out the perpendicular forces however and got a very similar answer. 2 - The weight of the bar and weight on the end act straight down, so I might need to somehow figure out a component of their force, but I have no idea how. If anyone could show me the working for the correct answer for this, it would be much appreciated. Cheers.
