Introduction To The Mechanical Principles Of Carpentry PDF Download

Excerpt from Elementary Principles of Carpentry, Vol. 6: A Treatise on the Pressure and Equilibrium of Timber Framing, the Resistance of Timber, and the Construction of Floors, Centres, Bridges, Roofs; Uniting Iron and Stone With Timber, Etc In the course of the last century several treatises on Carpentry have appeared; but in none of them is to be found any thing on the mechanical principles of the art, except it be a few rules for calculating the strength of timber; and these are founded upon erroneous views of the subject, and therefore are not to be relied upon. The greater part of the works on Carpentry are confined almost wholly to what is termed "finding the lines;" a branch of science to which the celebrated Monge gave the name of Descriptive Geometry: and in the works of Mr. P. Nicholson this part of Carpentry has been so ably handled, that little more seems required on the subject. But the knowledge of practical and descriptive geometry is not the only part of science that a carpenter ought to acquire; for when it is considered that the art of Carpentry is directed chiefly to the support of weight or pressure, it will be obvious that a considerable knowledge of the principles of mechanics is required to practise it with success. And it is not to carpenters alone that the study of the mechanical principles of Carpentry should be confined; for, in the modern practice of building, it forms one of the most important departments of the science of construction; and a knowledge of construction is so essential to the art of design, in Architecture, that it is difficult to believe how much it has been neglected, and how little it is esteemed by the students of that profession.
