TitleUnpublished paper, 'On the theory of internal resistance and of internal friction in fluids: and on the theories of sound and of auscultation' by Robert Moon
CreatorMoon; Robert (fl 1858-1868)
Date1858
DescriptionMoon shows that when sound is propagated along a cylindrical tube filled with air, the compression which takes place in any element calls forth a resistance which diminishes the velocity of the particles in the element, at the same time that the dilatation which takes place in any element calls into play a force which will tend to increase the velocity of the particles in the element. He considers that the amount of the force thus called into play in an element of given magnitude in a given indefinitely short interval, will depend solely on the amount of compression or dilatation developed in the element in the interval, and the state of density in the element at the time. He concludes with an ordinary equation for the transmission of sound through a column of air.

Annotations in pencil throughout. Includes one diagram in the text of an eardrum. Followed by a letter from Moon dated 1 April 1858.

Subject: Physics / Mechanics / Fluid dynamics / Differential calculus

Received 3 April 1858. Read 29 April 1858. Communicated by Arthur Cayley.

Written by Moon at 45 Cleveland Square, Hyde Park [London].

Whilst the Royal Society declined to publish this paper in full, an abstract of the paper was published in volume 9 of the Proceedings of the Royal Society as 'On the theory of internal resistance and internal friction in fluids ; and on the theories of sound and of auscultation'.
