1. 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?
