Book excerpt: Excerpt from A Treatise on Mechanics, Applied to the Arts, 1847: Including Statics and Hydrostatics It is impossible to arrange the parts of a demonstrative science in the order of their difficulty these first chapters will probably be found to present more difficulties to the student than any other por tion of the work. A thorough knowledge of the elementary principles discussed in them, is, nevertheless, a necessary introduction to the more practical parts of the science of Mechanics. Into every practical question of equilibrium, there enters the con sideration of weight; the mass held in equilibrium, whatever other forces may be applied to it, being necessarily subject to the action of the force of Gravity. A d? Assion of the influence of the weight acting in every portion of the mass of a body, upon the conditions of its equilibrium; and of the properties of its centre of gravity through which this weight may be supposed, in every position of the body, to act; constitutes, there fore, the subject of the next, or Fourth Chapter of the work. There is scarcely any case of equilibrium, among the forces com posing which, there do not enter two or more resistances of the surfaces of bodies in contact. The question of the resistances of the surfaces of bodies, constitutes, therefore, the subject of the Fifth Chapter. The method of treating it is altogether new. It is shown, that force applied to the surface of one body by the intervention of the surface of another, is destroyed, however great it may be, provided its direction lie within a certain right cone; having its vertex at the point of contact, and its axis perpendicular to the touching surfaces: and that it is not destroyed, however small it may be, provided its direction lie without that cone. It is by means of this property, that allowance is made for what is usually termed, friction - which is in reality, no other than the difference of the case of the resistance of a surface, as it actually obtains in nature, from the hypothetical case of resistance only in the direction of a normal: which hypothetical case, introduced in the infancy of the science, and intended to facilitate its first deductions, has been most unaccountably retained as a principle of equilibrium.
