ONE:3. The strains to which shafts are subjected are the torsional strain of transmission, transverse strain from belts and wheels, and strains from accidents, such as the winding of belts.He pitched the glittering gauds contemptuously on the desk. Leona examined them carefully So far as she could see no change had been made. And where the stones had been filed she could see the dull scratched edges. Was this the work of the hidden enemy or another cruel stroke of ill fortune?

ONE:And this one he particularly wanted to see, because the name was unknown to him. In all the swindlers in London it was the first time Prout had heard of one called "Frenchy." And the particular member of the gang--absent from London on business--seemed to be the leader of them all. Once Frenchy showed himself, Prout would give the sign, and within an hour the gang would be laid by the heels.Draughting, or drawing, as it is more commonly called, is a means by which mental conceptions are conveyed from one person to another; it is the language of mechanics, and takes the place of words, which are insufficient to convey mechanical ideas in an intelligible manner.

Even in his much-admired criticisms on the actually existing types of government our philosopher shows practical weakness and vacillation of character. There is a good word for them all��for monarchy, for aristocracy, for middle-class rule, and even for pure democracy.183 The fifth book, treating of297 political revolutions, is unquestionably the ablest and most interesting in the whole work; but when Aristotle quits the domain of natural history for that of practical suggestions, with a view to obviate the dangers pointed out, he can think of nothing better than the old advice��to be moderate, even where the constitutions which moderation is to preserve are by their very nature so excessive that their readjustment and equilibration would be equivalent to their destruction. And in fact, Aristotle��s proposals amount to this��that government by the middle class should be established wherever the ideal aristocracy of education is impracticable; or else a government in which the class interests of rich and poor should be so nicely balanced as to obviate the danger of oligarchic or democratic injustice. His error lay in not perceiving that the only possible means of securing such a happy mean was to break through the narrow circle of Greek city life; to continue the process which had united families into villages, and villages into towns; to confederate groups of cities into larger298 states; and so, by striking an average of different inequalities, to minimise the risk of those incessant revolutions which had hitherto secured the temporary triumph of alternate factions at the expense of their common interest. And, in fact, the spontaneous process of aggregation, which Aristotle did not foresee, has alone sufficed to remedy the evils which he saw, but could not devise any effectual means of curing, and at the same time has bred new evils of which his diagnosis naturally took no account.

To follow the same chain of reasoning still farther, and to show what may be gained by method and system in learning mechanics, it may be assumed that machine functions consist in the application of power, and therefore power should be first studied; of this there can be but one opinion. The learner who sets out to master even the elementary principles of mechanics without first having formed a true conception of power as an element, is in a measure wasting his time and squandering his efforts.44
