IMHO, any lateral force would make this collapse. Nodes 1234 indeed create a statically determinate body. However, the rod 3-5 and 4-6 are parallel and of equal length. Therefore body 1234 can freely rotate. Regarding how you show that mathematically, (without knowing the context of your assignment): 1234 is a rigid body you can substitute 1234 with a ...

TL;DR: Real life equations are created by carefully observing relationships between different quantities, making simplification assumptions, and then abstracting them into a mathematical form. I've posted below a few examples of how to derive DE's from "real life" examples for a range of sciences. Hopefully, they will give a glimpse of the process. ...
