So, I have a question regarding the method of joints used to solve force members in a truss. I am just starting the question and I am stuck on determining the moment in the support reactions.

So my questions are:

(1) For the moment around support reaction E do I include Force Dx in my equation?
So, [+Dx * 5]

(2) When finding the forces in the X direction is there a force in the Ex direction?

Thank you.
