Felix Mendelssohn-Bartholdy); and Nathan (a mechanical engineer of considerable repute).
Though we can convert the whole of the energy possessed by any mechanical system into heat, it is not in our power to perform the inverse operation, and to utilize the whole of the heat in doing mechanical work.
The genius of the modern pianoforte is to produce richness by depth and variety of tone; and players who cannot find scope for such genius in the real part-writing of the 18th century will not get any nearer to the 18th-century spirit by sacrificing the essentials of its art to an attempt to imitate its mechanical resources by a modern tour de force.
"Damian," came the mechanical voice.
His touch was mechanical and instructional, his attention elsewhere.
The mechanical laws, to which external things were subject, were conceived as being valid only in the inorganic world; in the organic and mental worlds these mechanical laws were conceived as being disturbed or overridden by other powers, such as the influence of final causes, the existence of types, the work of vital and mental forces.

Beyond a certain limit no mechanical disruption of the body could hasten the process of decomposition.
"I am well, ikir," came the mechanical reply.
In most mechanical systems the working stresses acting between the parts can be determined when the relative positions of all the parts are known; and the energy which a system possesses in virtue of the relative positions of its parts, or its configuration, is classified as "potential energy," to distinguish it from energy of motion which we shall presently consider.
The word potential does not imply that this energy is not real; it exists in potentiality only in the sense that it is stored away in some latent manner; but it can be drawn upon without limit for mechanical work.
Him succeeded, not only in showing that such a difference exists, but in measuring it, and hence determining a tolerably approximate value of the mechanical equivalent of heat.
The ratio of the portion of the energy of a system which can under given conditions be converted into mechanical work to the whole amount of energy operated upon may be called the "availability" of the energy.
When actually lifting at full speed the mechanical work of lifting represents about 72%° of the electric energy put into the lifting motor.
The strain of the next three years' continuous work undermined his health and his eyesight, and he was compelled to retire from his professorship. During these years he had published works on Plato and Socrates and a history of philosophy (1875); but after his retirement he further developed his philosophical position, a speculative eclecticism through which he endeavoured to reconcile metaphysical idealism with the naturalistic and mechanical standpoint of science.
It sounds mechanical, sterile, and just a little bit un-American.
I gave her my braille slate to play with, thinking that the mechanical pricking of holes in the paper would amuse her and rest her mind.
He is said to have fixed on a large and fully laden ship and to have used a mechanical device by which Hiero was enabled to move it by himself: but accounts differ as to the particular mechanical powers employed.
61, p. 444), and the instrument contains many elegant mechanical and optical details due to Horace Darwin and Messrs Zeiss respectively.
Descartes began with the certainty that we are thinking beings; that region remains untouched; but up to its very borders the mechanical explanation of nature reigns unchecked.
It is one of the grandest hypotheses which ever have been formed to account by mechanical processes for the movements of the universe.
The conclusions at which he arrives have not been so useful as he imagined, in consequence of the mechanical difficulties.
The doctrine of the circulation of the blood, which Descartes adopted from Harvey, supplied additional arguments in favour of his mechanical theory, and he probably did much to popularize the discovery.
From the brain these spirits are conveyed through the body by means of the nerves, regarded by Descartes as tubular vessels, resembling the pipes conveying the water of a spring to act upon the mechanical appliances in an artificial fountain.
Such is the reflex and mechanical movement independent of the mind.
Borelli (1608-1679) as its most notable name, entered in a way on the mechanical study of anatomy suggested by Descartes, but was probably much more dependent upon the positive researches of Galileo.
He carried out a number of magnetic investigations which resulted in the discovery of many interesting phenomena, some of which have been rediscovered by others; they related among other things to the effect of mechanical strain on the magnetic properties of the magnetic metals, to the relation between the chemical composition of compound bodies and their magnetic properties, and to a curious parallelism between the laws of torsion and of magnetism.
Diodorus says that the rock at the back of the palace containing the royal sepulchres is so steep that the bodies could be raised to their last resting-place only by mechanical appliances.
His faith made him believe that his adversaries were in the wrong; but how great must have been this faith, which permitted him to undertake the work at a time when mechanical appliances for the execution of such an undertaking did not exist, and when for the utilization of the proposed canal there was as yet no steam mercantile marine !
The institute comprises an academic department (in which all students are enrolled) with a seven years' course, the Phelps Hall bible training school (1892), with a three years' course, and departments of mechanical industries, industries for girls, and agriculture.
E14/YyaCa; Ev, in, €pyov, work), in physical science, a term which may be defined as accumulated mechanical work, which, however, may be only partially available for use.
This leads up to the fundamental distinction, introduced by Lord Kelvin, between "available energy," which we can turn to mechanical effect, and "diffuse energy," which is useless for that purpose.
By ca-sing two conical surfaces of cast-iron immersed in mercury and contained in an iron vessel to rub against one another when pressed together by a lever, Joule obtained 776.045 foot-pounds for the mechanical equivalent of heat when the heavy weights were used, and 774.93 foot-pounds with the small driving weights.
He also determined a roughly approximate value for the mechanical equivalent of heat from the results of these experiments.
And as there is no branch of art in which mechanical improvements, and the consequent change in the nature of technical difficulties, bear so directly upon the possibilities and methods of external effect, it follows that an exclusive preponderance of this view is not without serious disadvantage from the standpoint of general musical culture.
(The mechanical improvements by which horns and trumpets acquired a complete scale have revolutionized the nature of those instruments; and Wagner's orchestration, more than that of any other composer, has profited by this.
Often, listening to the pilgrims' tales, she was so stimulated by their simple speech, mechanical to them but to her so full of deep meaning, that several times she was on the point of abandoning everything and running away from home.

One of the first who took in hand the determination of the mechanical equivalent of heat was Marc. Seguin, a nephew of J.
In 1839 Seguin endeavoured to determine the mechanical equivalent of heat from the loss of heat suffered by steam in expanding, assuming that the whole of the heat so lost was consumed in doing external work against the pressure to which the steam was exposed.
Cranes driven by shafting, or by mechanical power, have been largely superseded by electric cranes, principally on account of the much greater economy of transmission.

She was already perfectly familiar with words and the construction of sentences, and had only mechanical difficulties to overcome.
Why is it only described as a mechanical device divorced from any purpose?
The conception of work and of energy was originally derived from observation of purely mechanical phenomena, that is to say, phenomena in which the relative positions and motions of visible portions of matter were all that were taken into consideration.
