In 1855 he published a memoir of Thomas Young, and about the same time there appeared Young's collected works in three volumes, for the first two of which Peacock was responsible.
Young's Chronicles of the Pilgrim Fathers (Boston, 1841); and E.
Young's condemnation of these survivals was as pronounced as his support of the methods of the large farmers to whom he ascribed the excellence of the husbandry of Kent, Norfolk and Essex.
The whole of the rod will therefore be subject to a compressive longitudinal stress P, the associated contraction R, expressed as a fraction of the original length, being R = P/M = (B 2 -H2)/87-M, where M is Young's modulus.
2 The results are too numerous to discuss in detail; some of those to which special attention is directed are the following: In Swedish iron and tungsten-steel the change of elastic constants (Young's modulus and rigidity) is generally positive, but its amount is less than 0.5%; changes of Young's modulus and of rigidity are almost identical.
In nickel the maximum change of the elastic constants is remarkably large, .amounting to about 15% for Young's modulus and 7% for rigidity; with increasing fields the elastic constants first decrease and then increase.
Versifiers and adapters from the French appeared also in Counts Adam and Joseph Teleki, Alexander Baroczi and Joseph Peczeli, known also as the translator of Young's " Night Thoughts."
3 The power of a grating to construct light of nearly definite wavelength is well illustrated by Young's comparison with the production of a musical note by reflection of a sudden sound from a row of palings.
The later investigations of Richard Potter and especially of Sir George Biddell Airy have proved the correctness of Young's idea.
At one time it was thought that these mixtures of constant boiling-point (an extended list is given in Young's Fractional Distillation) were definite compounds.
Young's Around the World with General Grant (New York, 1880); Horace Porter's Campaigning with Grant (New York, 1897); James Ford Rhodes's History of the United States (vols.
In 1797 he published a translation of Young's Night Thoughts, which does not of itself show that he was well acquainted with English, for the version may have been made with the help of the French.
(1805); Young's Coll.
But if y is the displacement at A, dy/dx is the extension at A, and the force acting is a pull across A equal to Y&uodyldx, where Y is Young's modulus of elasticity.
There are shears of the order dry/dx and the simple Young's modulus system can no longer be taken to represent the actual condition (see Rayleigh, Sound, i.
Young's modulus may be obtained for the material of a rod by clamping it in the middle and obtaining the frequency of the fundamental when Y = 412n2p.
Rods of different materials may be used as sounders in a Kundt's dust tube, and their Young's moduli may be compared, since: length of rod Then dO U = - ax dx or dt = - UK.
It had served to draw Young's attention to the question of oil-production, and in 1850 he took out his fundamental patent for the distillation of bituminous substances.
For a very full list of the papers and works of these early electrical philosophers, the reader is referred to the bibliography on Electricity in Dr Thomas Young's Natural Philosophy, vol.
The land policy of previous govern- Young's ments was entirely revised, and the Land Bill, framed by Sir John Robertson, introduced the principle of deferred payments for the purchase of crown lands, and made residence and cultivation, rather than a sufficient price, the object to be sought by the crown in alienating the public estate.
