Hello to all!
I have this one and only obligatory FEM-course and tbh I'm having some hard time with it,
so I'm hoping that someone can help me out with this assignment.
Define maximum allowed distributed load p when the own weight of the frame is taken into account. (Own weight is NOT included in p).
Use beam-elements of 2-dof.
(this must be solved with pen and paper so using e.g. Ansys isn't an option here)

KQ = F
K= global stiffness matrix
Q= displacement matrix
F= load matrix
I have a feeling that first step would be to obtain the global stiffness matrix K.
Then, knowing the yield strength and max. allowable stress we are able to obtain the displacement matrix Q. (Are we?)
And then solve the load matrix F with KQ = F ?
Thanks in advance!
