I have uploaded the problem here as a diagram is included
Summation of forces =0
summation of moment=0
The Attempt at a Solution
So basically what im trying to do is break up the problem and solve for segment CD then solve for segment DE. But im getting different answers compared to my friends.Im not including any forces at CD when i solve .Is there an external force of AC on CD and Force BD on CD.Please can someone explain. basically when i can solve for E i solve for A using moment at A while taking the whole frame as a whole.
