![CONSTRUCTION—Mechanics [ Because this book is designed chiefly to aid those who have not yet mastered a satisfactory vocation, technical questions have been omitted from these tests. ] Construction—Mechanies is that degree of Con- structive ability that enables one to make practical use of that branch of physics which treats of the action of the physical forces—heat, light, chemical action, electricity, gravity, magnetism and the motions of sound—on material bodies. Mechanics deals with these physical forces and their mathematical and power relations in sub- stances in solid states and in active states. The former, called statics—meaning to stand—is spoken of as the mechanics of rigid bodies, as the tensil strength of steel,.iron and stone; the latter, called dynamics—to exert sensible energy—is spoken of as the mechanics of hydrodynamics and hydraulics which treat of the powers and forces of fluids and gases, aS In waterpower, gas engines and steam engines, and as the mechanics of pneumatics which treats of the mechanical use of air and acoustics, the science of sound motions. Knowledge of the common elements of these branches and of the machinery used in their ex- pression is the basis of the simpler trades and of our ordinary activities in the arts and sciences. Mechanics is the most technical expression of the Construction ability. Such expression is funda- mentally necessary in many of the great con- structive vocations, as railroading, mine engineer-](https://iiif.wellcomecollection.org/image/b32755119_0040.jp2/full/800%2C/0/default.jpg)
