The 6575-lb engine is suspended from the crane boom. Assume the initial weight of members CD and AB to be 10lb/ft and 50lb/ft.

Determine the resultant internal loadings acting on the cross section of the boom at point E. Also, find the joint reactions at A, C and D.

So far I solve for the reactions at E. I am not sure what to do with the weight of members CD and AB. For now I have just added the weight of AB onto the end of my moment and Forces in the Y direction equations.
Is this correct?

Attached is my work and a picture of the boom.

gravity = 32.2

It is not clear what you mean by the reaction at E.

You are given the weights of both the crane boom and the diagonal support.
Figure out where these loads are applied, then determine what the reactions are at
points A, C,and D.
 
Post mangled beyond recognition by forces unknown.
