In the attached problem, I don't understand why members CD and DE are equal to 0. I was under the impression that the combined vertical components of BC and CD should equal 6+downward components of BC and EF, as to counteract the force straight down, but this is not the case.
My questions:
Why are the forces in members CD and DE equal to zero?
If they are equal to 0, what stops the downward force from moving the structure?
Thank you
Note: G and Ay are 6 and 6, not 8 and 6 as shown. I used the right values for my calculations, but for some reason wrote 8 down
