Las obras de Arquímedes

Entonces, puesto que CO = ½p, CL debe ser perpendicular a PT y, por tanto, a la superficie del fluido.

Y las fuerzas que actúan sobre la parte sumergida del paraboloide y sobre la parte situada por encima de la superficie actúan, respectivamente, hacia arriba y hacia abajo, a lo largo de rectas que pasan por F y H y son paralelas a CL.

Por tanto, el paraboloide no puede permanecer en la posición en que B apenas toca la superficie, sino que debe girar en el sentido de aumentar el ángulo PTM.

La demostración es la misma cuando el punto I no está en VP, sino en su prolongación, como en la segunda figura*.

Diagrama geométrico del original

[Con la notación de la p. 266, si la base BB′ toca la superficie del fluido en B, tenemos

BM=BVsinθ+PN

y, por la propiedad de la parábola,

BV2=(p+4AN)PV=pk(1+cot2θ)

Por tanto

ph=pk+p2cotθ

Para obtener el resultado de la proposición, debemos eliminar k entre esta ecuación y

x′−x=cosθ{p4(cot2θ+2)−23(h−k)}.

* Es curioso que las figuras de Torelli, Nizze y Heiberg sean todas incorrectas, pues sitúan el punto que he llamado I en BQ en vez de en la prolongación de VP.

Desktop + iOS client

Download the desktop app to work through scanned documents and export EPUB

The desktop app gives you a better place to inspect OCR text from scanned documents, review the exported EPUB, and keep the source file locally while you work. That is especially helpful when the source is document-like rather than a book.

Built for scanned documents that need a cleaner reading format

For scanned documents, the goal is usually to make the content easier to read, search, revisit, and keep using after OCR and export.

  1. Best for scanned manuals, notes, and reference documents

    Useful when the source is a document-style scan and the goal is a more readable EPUB format for reference or study.

  2. The output should be easier to reuse

    Searchers here usually want more than a new extension. They want a document that becomes easier to browse, revisit, and read.

  3. Review helps before the file becomes part of your workflow

    Users often still want to inspect OCR quality and decide whether the EPUB is good enough for regular reference.

  4. Focused on practical document reuse

    It stays useful for manuals, notes, and reference files where readability and repeat access matter more than simple file conversion.
