Can someone help me dismembering the frame!

im confused how to make them on for example ABC

IS that right? i made AG without x and y cause i gues we know it is along member ag since AG is a two force member?

Can someone check if that is right!


and IF IT IS RIGHT, can i just take moment about point A so everything cancels out except force at C and Y component of B?

can I do that?? to find By?

Your free body diagram of member ABC is correct. AG is a two-force member so you automatically know the direction in which the force is applied. Taking the sum of moments about point A must be zero and thus you could solve for the vertical component of the reaction at B, correct.

What is the overall goal of this problem? As in, what force are you trying to solve for?

I would suggest that it is important to clarify what is meant by "dismembering frames." In structural engineering, dismembering a frame refers to the process of breaking down a frame structure into smaller, more manageable components for analysis. It is an important step in structural analysis and design.

Regarding the provided images, it appears that the individual is trying to analyze a frame structure and is unsure of how to approach it. It is important to understand the forces and moments acting on the frame in order to accurately analyze it. The first step would be to identify all the members and their orientations, as well as the external forces and moments acting on the frame.

In the second image, it seems that the individual has correctly identified member AG as a two-force member. However, it is important to also consider the reactions at points A and B in order to accurately analyze the frame. Taking moments about point A to find the force at point C and the Y component of force at point B may be a valid approach, but it is important to double check the calculations and ensure that all forces and moments are properly accounted for.

In conclusion, dismembering a frame is an essential step in analyzing and designing structures. It is important to have a clear understanding of the forces and moments acting on the frame in order to accurately analyze and design it. Taking moments about a specific point can be a valid approach, but it is important to double check calculations and consider all forces and reactions in order to ensure accuracy.
