Notes On Rankines Applied Mechanics Part I PDF Download

Excerpt from Notes on Mechanics, Vol. 1: Designed to Be Used in Connection With Rankine's Applied Mechanics; Part I. Statistics The fundamental idea of Mechanics is Motion. Force, as far as we have to consider it, may he defined as that which causes, or tends to cause, a body to change its state from rest to motion, or vice versa, or to change its motion as to direction or speed. Statics is that part of Mechanics which considers the relations of forces as producing pressures, or a tendency to motion. Dynamics considers forces as producing motion. Motion is a fundamental idea; it might be defined as change of position. Motion, as far as our senses are capable of recognizing it, is relative. We cannot tell whether anything in the universe is absolutely at rest or not. All bodies on the earth partake of its motion, and hence even those that seem to he at rest when compared with the position of the earth, are really in motion. A person sleeping on a steamer is at rest with reference to the steamer, but in motion with reference to the earth. Hence we always assume some point as fixed; relatively to which we determine whether a body is in motion or at rest.
