The discussion focuses on the challenges of drawing accurate free body diagrams for statics problems involving frames and machines. Key errors identified include incorrect representation of loads and omission of reaction forces from walls. The distributed load is clarified as a maximum of 4kN/m at the center, reducing linearly towards the edges. Participants emphasize the necessity of including wall reactions to achieve correct solutions.
PREREQUISITESStudents and professionals in engineering, particularly those studying statics, structural analysis, and mechanics of materials, will benefit from this discussion.
I see two errors in your AB diagram.lc99 said:
Ohh. okay about ABharuspex said:
Ok, maybe I misunderstand the diagram. If it is to be interpreted as a load that is a maximum of 4kN/m in the middle, reducing linearly each side, then I agree with your number. Since it only specified 4kN/m I took the load to be constant.lc99 said:
If you post the link I will take a look, but in this thread I believe you need to includ those reactions.lc99 said:
here is the link. thank you! :)haruspex said:
Ok, I have posted an answer there, and you are making the same mistake in this thread.lc99 said:
