Description

Mechanics of Automobiles deals with the application of the basic theory of mechanics to certain problems arising from the motion of an automobile. This book is composed of 11 chapters and begins with an evaluation of various aspects of vehicle performance and brakes. The next chapters deal with other vehicle components, including dry friction clutches, gear box, non-axial shafts, cams, and valve gears. The remaining chapters discuss the balance of reciprocating engines, the different types of suspension and steering, the gyroscopic effects, and the role of vibrations in vehicles. This book will prove useful to research engineers, designers, and draftsmen employed in the automobile industry, as well as to higher and advanced level mechanical engineering students.
