Homework Help: Truss problem

  1. Nov 25, 2014 #1
    1. The problem statement, all variables and given/known data
    I've solved all but one force. I can't seen to get the force within element D-C. All relevant variables are shown on the pics attached i.e loads, supports, dimensions etc...

    2. Relevant equations
    Sum of forces in x=0, sum of forces in y=0, sum of moments=0

    Why don't you try applying the same methods that you used to find the forces at joints A and E to either joint C or joint D, this should give the force in the member CD
