Drawing a pulley system

I need to draw a pulley system as in the figure. How can I do that?

Specific information about the figure: A block of mass Mo is on a horizontal surface and attached by a string to a hanging block, also of mass Mo , as shown in the figure. Friction between the block and the horizontal surface is negligible. The masses of the string and pulley are negligible, and the pulley can rotate with negligible friction around its axle.

run with `lualatex`. Placing the text ist easy with `\rput`:

    \DocumentMetadata{}
    \documentclass[margin=50pt, varwidth]{standalone}
    \usepackage{graphicx}
    \usepackage{pstricks,pst-slpe}
    
    \begin{document}
    
    \begin{pspicture}[showgrid=top](10,8)% delete showgrid 
    %\psset{dimen=outer}
    \rput[lc]{45}(6.5,4.65){%
    	\psframe[framearc=0.5](0.05,0)(0.75,0.2)
        \psdot[dotscale=0.7](0.65,0.1)
        \pscircle(0.65,0.1){0.23}
    }
    \psline[linewidth=2\pslinewidth,linearc=0.24]%
       (7.1,3.5)(7.1,5.4)(4.5,5.4)
    \psframe[fillstyle=solid,fillcolor=white](0,4.7)(6.7,5)
    \psframe[fillstyle=slope,slopebegin=white,slopeend=black](3.1,5)(4.5,5.8)
    \psframe[fillstyle=slope,slopebegin=white,slopeend=black](6.7,2.1)(7.5,3.5)
    \psframe(6.2,0)(6.4,4.74)
    \psframe(0.4,0)(0.6,4.74)
    \psline(0.2,0)(9.5,0)
    \end{pspicture}
    
    \end{document}
