章節(jié)摘錄

版權(quán)頁(yè)：   插圖：    Mechanics can be defined as that branch of the physical sciences concerned with the state of rest or motion of bodies that are subiected to the action of forces.In general,this subject is subdivided into three branches：rigid-body mechanics,deformable-body mechanics,and fluid mechanics.This book treats only rigid-body mechanics since it forms a suitable basis for the design and analysis of many types of structural，mechanical，or electrical devices encountered in engineering.Also.rigid-body mechanics provides part of the necessary background for the studyof the mechanics of deformable bodies and the mechanics of fluids. Rigid-body mechanics is divided into two areas：statics and dynamics.Statics deals with the equilibrium of bodies,that is, those that are either at rest or move with a constant velocity；whereas dynamics is concerned with the accelerated motion of bodies,Although statics can be considered as a special case of dynamics，in which the acceleration is zero，statics deserves separate treatment in engineering education since many objects are designed with the intention that they remain in quilibrium.Historical Development. The subject of statics developed very early in history because the principles involved could be formulated simply from measurements of geometry and force. For example, the writings of Archimedes （287-212 B.C.） deal with the principle of the lever. Studies of the pulley, inclined plane, and wrench are also recorded in ancientwritings--at times when the requirements of engineering were limited primarily to building construction. Since the principles of dynamics depend on an accurate measurement of time, this subject developed much later. Galileo Galilei （1564-1642）was one of the first major contributors to this field. His work consisted of experiments using pendulums and falling bodies. The most significant contributions in dynamics, however, were made by Issac Newton （1642-1727）, who is noted for his formulation of the three fundamental laws of motion and the law of universal gravitational attraction. Shortly after these laws were postulated, important techniques for their application were developed by Euler, D'Alembert, Lagrange, and others.
