# How to use *Rankine* in a sentence

The standard of comparison generally adopted for this purpose is obtained by calculating the efficiency of an engine working according to the

**Rankine**cycle.These writings, however, corresponded to but one phase of

**Rankine**'s immense energy and many-sided character.Patten in 1824; whilst in 1881

**Rankine**Kennedy resuscitated the idea for the purpose of exhausting filament electric lamps.One or two chapters on the subject are also generally included in treatises on the steam engine, or other heat engines, such as those of

**Rankine**, Perry or Ewing.Of greater interest, particularly from a historical point of view, are the original papers of Joule, Thomson and

**Rankine**, some of which have been reprinted in a collected form.Advertisement**Rankine**proved (Applied Mechanics, p. 370) that the necessary strength of a stiffening girder would be only one-seventh part of that of an independent girder of the same span as the bridge, suited to carry the same moving load (not including the dead weight of the girder which is supported by the chain).**Rankine**gives the approximate rule Working deflection =5= l a /t o,000h, where l is the span and h the depth of the beam, the stresses being those usual in bridgework, due to the total dead and live load.**Rankine**, was therefore much vivified by Lord Kelvin's specification (Comptes Rendus, 1889) of a material gyrostatically constituted medium which would possess this character.The first accurate calculations of the specific heats of air and gases were made by

**Rankine**in a continuation of the paper already quoted.S = 475, greatly increased the apparent discrepancy between Regnault's and

**Rankine**'s formulae for the total heat.AdvertisementThe formulae of

**Rankine**and Unwin, though probably less accurate over the whole range, are much simpler and more convenient in practice than that of Biot, and give results which suffice in accuracy for the majority of purposes.The approximate equation of

**Rankine**(23) begins to be I or 2% in error at the boiling-point under atmospheric pressure, owing to the coaggregation of the molecules of the vapour and the variation of the specific heat of the liquid.The practical application of mechanics may be divided into two classes, according as the assemblages of material In view of the great authority of the author, the late Professor Macquorn

**Rankine**, it has been thought desirable to retain the greater part of this article as it appeared in the 9th edition of the Encyclopaedia.The question was investigated by

**Rankine**in an article in the Engineer (April 9, 1869).In 1871 the late Professor

**Rankine**, F.R.S., whose remarkable perception of the practical fitness or unfitness of purely theoretical deductions gives his writings exceptional value, received from Major Tulloch, R.E., on behalf of the municipality of Bombay, a request to consider the subject generally, and with special reference to very high dams, such as have since been constructed in India.Advertisement**Rankine**pointed out that before the vertical pressure reached the maximum pressure permissible, the pressure tangential to the slope might do so.Next,

**Rankine**pointed out that, in a structure exposed to the overturning action of forces which fluctuate in amount and direction, there should be no appreciable tension at any point of the masonry.**Rankine**in his report adopted the prudent course of taking as the safe limits certain pressures to which, at that time, such structures were known to be subject.For simplicity of calculation

**Rankine**chose logarithmic curves for both the inner and outer faces, and they fit very well with the conditions.After

**Rankine**, a French engineer, Bouvier, gave the ratio of the maximum stress in a dam to the maximum vertical stress as 1 to the cosine squared of the angle between the vertical and the resultant which, in dams of the usual form, is about as 13 is to 9.Advertisement**Rankine**died at Glasgow on the 24th of December 1872.
