The discussion revolves around a statics problem involving free body diagrams for frames and machines. The original poster is attempting to determine the reaction forces at a specific point and is confused about the proper representation of the free body diagrams for various members.
Some participants have identified specific errors in the diagrams and are engaging in clarifying the nature of the loads involved. There is an ongoing exploration of how to correctly interpret the load distribution and the necessary reactions from supports.
Participants are referencing a previous similar problem and discussing the need to include wall or floor reactions in the diagrams. There is uncertainty regarding the interpretation of the load as either constant or varying, which is affecting the analysis.
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:
