AI Thread Summary
The discussion revolves around a request for assistance in drawing a triangle of forces for joint A in a physics problem. The user has attempted to set up equations for the forces in both the x and y directions but is struggling to arrive at the correct answer. Another participant redirects the conversation by asking for an equation that connects the force in member AC to its components. This indicates a focus on understanding the relationships between forces in a structural analysis context. The thread highlights the challenges of solving force equilibrium problems in engineering.

Are you able to draw a triangle of forces for the joint A?
 
i did try this..
Fx = 0
Fxa=Fxb+fxc

Fy=o
Fya=Fxb+fxc

but i cannot get the right answer...
 
You didn't answer my question. However, try this one. For the member AC alone, can you write an equation linking the force in it to its components?
