Hi guys, i hope this is posted in the right area, i have been struggling on the following question. Sorry about the diagram but i dont have a scanner

I have a pin frame BCFGD and need to resolve the forces. It is attached to a wall at B and F. There is a negative force of 20KN acting vertically at C and at D a positive force of 10KN acting horizontally.

2. Relevant equations

3. The attempt at a solution

I have worked out the following BC=20KN, CF=28.28KN, FG=10KN, CG=40KN GD=10KN

I think i am on the right line but I just cant get it to add up. I started by working out the forces at the supports which i got as 20KN for B and 10KN for F acting horizontally and a vertical force of 20KN acting at F.

Any help would be appreciated
