Summary[edit]

Description
English: Photo of 36 Johansson gauge blocks wrung together and held horizontally, from a 1907 toolmaking book. The blocks are held together solely by the adhesion of their extremely flat surfaces, which is so strong that it easily supports their weight. Caption of photo: "Thirty-six gages wrung together and held horizontally". Alterations to image: removed caption, increased brightness, increased contrast.
Deutsch: Foto von 36 Johanssonschen Endmaßen, die zusammengefügt wurden und horizontal gehalten werden, aus einem Buch über Werkzeugherstellung von 1907.

Die Endmaße werden nur durch die Adhäsion zwischen ihren extrem planen Oberflächen zusammengehalten, welche ohne Weiteres ausreicht, um ihr eigenes Gewicht zu tragen. Die originale Bildunterschrift lautet, übersetzt aus dem Englischen: "Sechsunddreißig Endmaße zusammengefügt und horizontal gehalten".

Veränderungen zum Originalscan: Bildunterschrift entfernt, Helligkeit und Kontrast erhöht.
