Description
English: Diagram of a Gravesande ring, an experiment demonstrating thermal expansion which is used in physics education. It consists of a small metal ball suspended from a stand by a chain. Below it is a metal ring. The ring is just big enough so when the ball and ring are at the same temperature, the ball can just fit through the ring. However, when the ball is heated by a spirit lamp as shown here, the metal expands and it's diameter increases, so it can no longer fit through the ring.

2o L’expérience suivante, connue sous le nom d’expérience de S’ Gravesande ( 1 ), établit que les corps solides non cris- tallisés demeurent semblables à eux-mêmes en se dilatant. Une sphère métallique (fig. 2) passe librement à travers un anneau de même substance qui l’embrasse suivant un grand cercle. Si l’on vient à chauffer la boule sans modifier la tem- pérature de l’anneau, on constate qu’elle ne peut plus le tra- verser ; mais elle est demeurée sphérique, et ce qui le prouve,

( 1 ) S’ Gravesande, Physices elementa mathematica experimentis confirmata, sive Introductio ad Philosophiam Newtonianam ; Genève, 1778, t. II, p. 660.

c’est qu’elle touche l’anneau sur tout son contour. D’ailleurs, dès que la sphère s’est mise en équilibre de température avec l’anneau, elle le traverse de nouveau sans difficulté.

Si l’on échauffe à la fois la sphère et l’anneau, celui-ci ne cesse pas d’embrasser exactement la sphère suivant un grand cercle : un solide creux se dilate donc comme s’il était plein.

Licensing

This is a faithful photographic reproduction of a two-dimensional, public domain work of art. The work of art itself is in the public domain for the following reason:
Public domain

This work is in the public domain in its country of origin and other countries and areas where the copyright term is the author's life plus 70 years or fewer.

You must also include a United States public domain tag to indicate why this work is in the public domain in the United States.
 Note that a few countries have copyright terms longer than 70 years: Mexico has 100 years, Jamaica has 95 years, Colombia has 80 years, and Guatemala and Samoa have 75 years. This image may not be in the public domain in these countries, which moreover do not implement the rule of the shorter term. Honduras has a general copyright term of 75 years, but it does implement the rule of the shorter term. Copyright may extend on works created by French who died for France in World War II (more information), Russians who served in the Eastern Front of World War II (known as the Great Patriotic War in Russia) and posthumously rehabilitated victims of Soviet repressions (more information).
This file has been identified as being free of known restrictions under copyright law, including all related and neighboring rights.
The official position taken by the Wikimedia Foundation is that "faithful reproductions of two-dimensional public domain works of art are public domain".
This photographic reproduction is therefore also considered to be in the public domain in the United States. In other jurisdictions, re-use of this content may be restricted; see Reuse of PD-Art photographs for details.
