Excerpt from Principles and Construction of Machinery: A Practical Treatise on the Laws of the Transmission of Power, and of the Strength and Proportions of the Various Elements of Prime Movers, Mill-Work, and Machinery Generally; Arranged for the Use of Students, Engineers, and Practical Mechanics
Sufficient examples are given in the first portions of the book to show the method of using symbolical formul?, wherefore in the latter parts the formul? are not all illustrated by arithmetical examples, as to have followed such a course would have inconveniently extended the bulk of the volume.
The Author's aim throughout has been, in the first place, to explain the Fundamental Theories of Mechanism in the clearest and briefest manner, so as to impress upon the mind general principle, not special cases, and then to show the practical development of such theories, care being taken so to arrange the matter as to try the faculties of the mind as little as possible.
