## Homework Statement

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.
