您的问题是“为我做”问题之一......
编辑:无论如何,@AboAmmar 快了几秒钟,而且几乎给出了相同的解决方案。所以在不知该怎么做时,我先删除我的答案,然后激活,再次删除,最后,由于差异很小,我决定激活它。
上图是由以下人员绘制的:
\documentclass[border=3mm,
tikz,
]{standalone}
\usetikzlibrary{decorations.pathmorphing}
\begin{document}
\begin{tikzpicture}[
decoration={coil,amplitude=3mm,segment length=3mm}
]
\draw (0,0) circle (2);
\draw[decorate,thick,red] ( 95:2) arc ( 95:270:2);
\draw[decorate,thick,blue] (-85:2) arc (-85:90:2);
\fill[black] (0,-2) circle (3mm)
(0, 2) circle (3mm);
\draw[thick,<->] (70:2.6) arc (70:110:2.6) node[above,midway] {$F_d(t)$};
\end{tikzpicture}
\end{document}
答案2
尝试这个decoration
方法:
\documentclass[tikz]{standalone}
\usetikzlibrary{decorations.pathmorphing}
\begin{document}
\scriptsize
\begin{tikzpicture}
\draw (0,0) circle (1cm);
\draw[decorate,decoration={coil,segment length=4pt},rotate=92] (0,0) circle(1cm);
\draw[fill] (0,1) node[above=.2cm]{$F_d(t)$} circle(3pt) (0,-1) circle(3pt);
\draw [<->] (75:1.2cm) arc [radius=1.2cm, start angle=75, end angle=105];
\end{tikzpicture}
\end{document}
