Is this another statically indeterminate structure?

Click For Summary

Discussion Overview

The discussion revolves around determining whether a given structure is statically indeterminate. Participants explore the implications of the structure's configuration and forces acting on it, with a focus on solving a homework problem related to structural analysis.

Discussion Character

  • Homework-related
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • One participant interprets the structure as statically indeterminate and seeks confirmation or guidance on solving the problem.
  • Another participant argues that the structure is no longer indeterminate after considering the two force members connected to a specific part of the structure.
  • A question is raised regarding which tension is being referred to in the calculations, indicating potential confusion about the forces involved.
  • There is a challenge to the claim of having solved the question, emphasizing the need to account for all external forces and ensure equilibrium.
  • One participant expresses agreement with a solution presented, stating it is correct.

Areas of Agreement / Disagreement

Participants express differing views on whether the structure is statically indeterminate, with some asserting it is not while others maintain uncertainty. The discussion remains unresolved regarding the completeness of the solution and the verification of equilibrium.

Contextual Notes

Participants highlight the importance of considering all forces and moments in the analysis, suggesting that assumptions about the structure's behavior may depend on specific interpretations of the forces involved.

Homework Equations





The Attempt at a Solution



I interpret the question as a statically indeterminate structure. Am I correct? if not how to solve this question?

Thank you very much for your help! =)

after considerin the 2 force members connected to the "ruler", i realize its no longer indeterminate.

I resolved the reaction at B using moments at the intersection of tension and the force by de member.

And solve the tension to be 292.1 N.

(Question solved)

the intersection of which tension? The vertical one holding the 2000 N weight, or the inclined one at B? Or force FG?
 


FG and DE. note that DE is a 2 force member. hence the forces involved with it is horizontal.
 


I don't think you can claim 'question solved' until you have found ALL the external forces and checked they are in equilibrium up down and rotational. There's many a slip. I do get a different answer to you.
 


what do you have?
 
darkdream: Excellent work. Your answer is correct.
 


thanks a lot! =) nvn
