Discussion Overview

The discussion revolves around the calculations involved in determining the internal loadings and joint reactions in a crane boom statics problem, particularly focusing on how to account for the weights of the boom members in the analysis.

Discussion Character

  • Homework-related

Main Points Raised

  • One participant presents a scenario involving a suspended engine and the weights of crane boom members, seeking guidance on how to incorporate these weights into their calculations.
  • Another participant questions the clarity of the term "reaction at E" and suggests that the participant should identify where the loads from the boom members are applied before determining the reactions at points A, C, and D.
  • A third post appears to be incomplete or corrupted, providing no additional context or information.

Areas of Agreement / Disagreement

The discussion does not show clear agreement, as participants are addressing different aspects of the problem and there is uncertainty regarding the interpretation of the reactions and the application of loads.

Contextual Notes

There are limitations in the clarity of the original question and the completeness of the posts, particularly with the third post being mangled and lacking context.

Who May Find This Useful

This discussion may be useful for students or practitioners involved in statics and structural analysis, particularly those working with crane systems and load calculations.

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.

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.
