I am new with Tikz and I managed to combine several Tikz code samples [x] to represent a 3-degree of freedom system. However, I would like to 'translate'/move the pendulum from mass M to the second mass M2 but it doesn't work. The center of the pdf content seems to be defined at the M.center and the "definition" of angle as well. I did not achieve to change that as I tried to move the pendulum, the angle won't translate to the next mass M2.

Here is what I get:
Any sugestion would be welcome!
pgfplotspackage loadstikz, but requires to set thecompatoption. Do you needpgfplotsat all? You should use\tikzsetinstead of\tikzstyle. Also, you should probably not (re)define short commands like\Nin the global scope. – Jasper Habicht Dec 21 '23 at 10:03\picstatements, see https://tikz.dev/tikz-pics . Think of the as macros for Tikz. – MS-SPO Dec 21 '23 at 17:30pics as @MS-SPO suggested, but I'm not sure I'd recommend it if you've just started using TikZ.picshave some idiosyncrasies which may just introduce unnecessary confusion at this point. Better, I think, to work through the tutorials at the start of the TikZ manual first and draw some simple pictures with basic building blocks so you get a 'feel' for how things work first. – cfr Dec 21 '23 at 17:37
