Yes, that's it. Thank you very much. You've earned heaven (whatever heaven is to you) :)

I think that's it, I would have to do the algebra, but as far as it looks, looks fine

Yes, I know, and also there must be a rotational kinetic energy, I made the algebra considering that φ2 is measured from the vertical and obtained But even though I consider $$\phi_2=\phi_1+\phi'$$ I don't get to the equations of the second image

I must find the Lagrangian for an undamped pendulum using the diagram showed below, I've no idea what to do with the second angle φ2 because is measured from the line that joins the two pivot points. The ecuations I must obtain are as follows I get so many different things but I can't reach...
