Mechanics of Machinery By Mahmoud A. Mostafa

Description

download free Mechanics of Machinery Mahmoud A. Mostafa book in pdf format is intended to serve as a reference for students in the mechanical field and practicing engineers, and is concerned with the analysis of machines. This book discusses the kinematics and dynamics of mechanisms. It is intended as an informative guide to a more complete understanding of kinematics and its applications. It is hoped that the fundamental procedures covered here will transfer to problems the reader may encounter later. This book was developed from an earlier version published in 1973. That early version was based on graphical analysis, which did not meet the requirements of modern developments. This version includes analytical analysis for all the topics.

These analytical analyses makes it possible to use math software for fast, precise, and complete analysis. for download other free eBook click here.

Chapter 1 introduces several mechanisms to familiarize the reader with different motions and functions they can perform. Analytical analysis for the performance of the mechanism is also presented, which is adapted to use math software to facilitate the study of the performance of mechanisms.

Chapter 2  of download free Mechanics of Machinery written By Mahmoud A. Mostafa book in pdf format , deals with the study of velocities and accelerations in the mechanism. This is a necessary step for the design of machines. The graphical method, which is based on vector equations, is presented and is applied to different mechanisms. The graphical method gives insight to the velocities and accelerations for members in the mechanism. Also, analytical analysis is presented and adapted for use with math software for an overall study of the mechanisms. One distinct feature of this book is the analysis of sliding links using a theory developed by the author. It is a replacement for Coriolis components, which are generally difficult to apply in most cases.

The subject of cams is presented in Chapter 3. For specified motion cams, the pro- file is obtained by graphical method. To obtain the contour analytically, equations in Cartesian coordinates, which was developed by the author, is presented. Special emphasis is directed toward the factors affecting the cam design, such as the pressure angle and the radius of curvature.

Chapters 4 through 6  of download free Mechanics of Machinery written By Mahmoud A. Mostafa book in pdf format are devoted to giving a realistic study of the geometry and kinematics of all types of gears. The study of gear reduction units is very important for machine application. Chapter 7 is concerned with the study of force analysis in mechanisms. Force analysis is divided into three parts-static force analysis, friction force analysis, and dynamic force analysis. In this book, the traditional graphical method is used in addition to the analytical method. The analytical method lays down the foundation for using math software to perform the analysis.

Programs using MathCAD are presented for complete analysis of all kinds of mechanisms, which include position analysis, velocities and acceleration analysis, and force analysis. This chapter also includes the study of the torque variation and the use of flywheels to reduce the speed variation.

Chapter 8 of download free Mechanics of Machinery written By Mahmoud A. Mostafa book in pdf format | published in 2017 First edition covers the study of balancing of machines. It explains how to balance rotating parts and reciprocating parts. In-place balancing of machines using vibration measurements is also presented.
