AI Thread Summary
To account for member weights in crane boom statics calculations, the weight of members CD and AB must be incorporated into the equations for moments and forces. The reactions at points A, C, and D need to be calculated based on the applied loads, including the suspended engine and the weights of the members. It is essential to determine where the loads from members CD and AB are applied to correctly analyze the internal loadings at point E. The discussion emphasizes the importance of accurately including all forces in the calculations. Properly addressing these factors will lead to a more accurate assessment of the crane's structural integrity.

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.
