关于 Tikz 图片的帮助

Question

我需要的

我的尝试

我根本不擅长 tikz，所以你能帮我画这个可怕的东西吗？

我用了mathcha.io作为编辑（坏主意）代码

    \documentclass{standalone}
    \usepackage{tikz}

    \tikzset{every picture/.style={line width=0.75pt}} %set default line width to 0.75pt

Answer 1

这是一个您可以轻松扩展输出的尝试（之后需要担心一些细微的调整）：

\documentclass[border=3.14mm]{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows.meta}
\usetikzlibrary{patterns.meta}

\begin{document}
\begin{tikzpicture}[scale=1,transform shape]
    %Outer background with the text at the bottom
    \draw [draw=red, fill=orange,fill opacity=0.10] (-2.5, -1) 
    node[below, pos=0, yshift=-8pt, text=black, opacity=1] {Pmc.11} 
    rectangle (2.5, 6.5) ;
    %Blue background with the three lines
    \fill [cyan, fill opacity=0.33] (-2, 0) rectangle (2, 4.5);
    %Three-border outline
    \draw[black, very thick] (-2, 4.75) -- (-2, 0) -- (2, 0) -- (2, 4.75);
    %The circle and two blue lines
    \begin{scope}[shift={(0, 2)}]
        \clip (0, 0) circle (1cm);
        \draw[fill=white, very thick] (0, 0) circle (1cm);
        \draw[thick, dashed, blue] (-1,0.25) to[out=-40,in=-90] (1,-0.25);
        \draw[thick, dashed, blue] (-1,-0.5) to[out=-5,in=-30] (1,0.5);
    \end{scope}
    %The three arrows with labels
    \node[label={[label distance=-20pt,xshift=10pt]below:$m\vec{g}$}] at (0, 0) (a) {};
    \node[label={[label distance=-8pt,xshift=10pt]below:$\vec{F}_A$}] at (0, 3.5) (b) {};
    \node[label={[label distance=-10pt,xshift=-10pt]below:$\vec{T}$}] at (0, 4) (c) {};
    \node[] at (0, 5) (d) {};%top line
    \draw[-Stealth, red] (a) -- (b);
    \draw[Stealth-Stealth, red] (a) -- (c);
    \draw[blue,dashed, shorten <= -6pt] (c) -- (d);
    %The top hatched rectangle along with its background and
    % the bold black line at the bottom
    \draw[black,line width=2mm] (-1,5) -- (1,5);%bold line
    \fill [lightgray] (-1,5) rectangle (1,6);%background
    \fill [pattern={Lines[angle=0,distance=2pt]}, pattern color=black,inner sep=0pt] 
    (-1,5) rectangle (1,6);%hatched lines
\end{tikzpicture}
\end{document}
