Dismembering frames

    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?
