TitleUnpublished paper, 'Elementary considerations on the subject of rotatory motion' by William Gravatt
Date1856
DescriptionGravatt explains the subject of rotatory motion in a series of propositions by the use of prime and ultimate ratios. He commences with a simple problem, determining the law of the forces by which a particle of matter is deflected into any given course, and pursues the inquiry by a consideration of the effect of these forces as referred to a sphere, going on to the investigation of the character of the motion of any body enclosed within an imaginary sphere, such sphere itself being supposed to revolve upon two axes inclined at any angle to each other. Hence the author determines the position of some point of the circumscribing sphere momentarily at rest, or in other words, of the resultant axis, from which he insists that all centrifugal forces must really be calculated. Annotations in pencil throughout. Includes five figures in the text and a separate page of geometrical figures. Preceded by a covering letter dated 6 March 1856.
