Complete checks to find the support reactions, and establish that the framework is stable and statically determinate. Also, prepare using a suitable scale and annotation of a space diagram for the framework.
Space diagram of the system
What I have done is draw a space diagram for the given system. A space diagram is a diagram drawn to a scale. I have used a scale of 1 square = 1 meter. I have also added forces that act on this system.
I have also labeled each node using numbers from left to right, so they can be referred to. A node is where two or more members are connected together via a pin. I also labeled each space adjoining the members using upper case letters. The sequence of letters goes clockwise from outside to inside creating a spiral. Lastly, I have included the supported beams.
