Problem F6-11 Statics Hibbeler 12th (Chapter 6)

Determine the force in members GF, GD, and CD of the truss. State if the members are in tension or compression.
I apologize but I will not be doing the F6-12. I don't think it will be any more useful than the last three problems we have done. Thanks all!

the GFcos(26.6) component of the first moment equation should be multiplied by 2 26.25(2) + (2)GFcos(26.6) = 0

Useful insights, nice method. Thanks
