How to draw simple spring mass system?

Question

Can I get anybody to help me with drawing this spring mass system in LaTeX? I've tried using another code for a spring mass system in here, but unfortunately I can't get it modified as I want. Hopefully there is one of you guys, who is a bit more experienced than me.

Answer 1

As has been remarked in the comments there are zillions posts drawing such things. Many of them have some distinctive features. The only point that might be different in this code from many others is that it uses patterns.meta.

\documentclass[tikz,border=3mm]{standalone}
\usetikzlibrary{patterns.meta,decorations.pathmorphing}
\begin{document}
\begin{tikzpicture}[>=stealth]
 \path[pattern={Lines[angle=45,distance={8pt/sqrt(2)}]}] (-2,5) edge ++(4,0)
  rectangle ++ (4,0.5);
 \draw[decorate,decoration={coil,segment length=5pt,aspect=0.7,amplitude=4pt,
    pre=lineto,pre length=5mm,post=lineto,post length=5mm},thick] (0,5) -- (0,1)
    node[below,draw,minimum size=1cm,fill=blue!20](m){$m$};
 \draw[blue] (m.center-|0,0) ++ (0,1) -- ++ (-2,0) 
    edge[<-,edge label'=$x$,shorten >=1pt] (m.center-|-2,0)
  (m.center-|0,0) ++ (0,-1) -- ++ (-2,0) 
    edge[<-,edge label=$-x$,shorten >=1pt] (m.center-|-2,0)
    (m.east) edge[dashed] (m.east-|2,0) 
     (m.east-|2,0) node[right] {Equilibrium};
\end{tikzpicture}
\end{document}

I also want to add that if, as you say, you struggle to modify an existing code to fit your needs, it would IMHO make much more sense to show what you have tried. Then you could learn how you can modify posts to get what you need and thus able to create whatever you want without relying on the availability of others. This is particularly easy with TikZ because usually you only need to modify some keys/styles (and coordinates, of course).

Answer 2

If you like the drawing...you can create a fast code with TikZ using Matcha: https://www.mathcha.io/editor.
