is the FBD for my truss correct?

Except for the typo error for the load applied at C (should be 4.5, not 4), your FBD is excellent, nice work.

Now that I'm sure my FBD diagram and equilibrium equations are correct, I moved onto the actual truss analysis and I'm still not obtaining an equilibrium at all the joints within the truss.

Can anyone help me find my error?

This has been giving me quite the headache!

Thanks again.

EDIT: Fixed my error, got everything to work out ;)
