Focusing on how a machine "feels" and behaves while operating,
Machine Elements: Life and Design seeks to impart both intellectual
and emotional comprehension regarding the "life" of a machine. It
presents a detailed description of how machines elements function,
seeking to form a sympathetic attitude toward the machine and to
ensure its wellbeing through more careful and proper design. The
book is divided into three sections for accessibility and ease of
comprehension. The first section is devoted to microscopic
deformations and displacements both in permanent connections and
within the bodies of stressed parts. Topics include relative
movements in interference fit connections and bolted joints, visual
demonstrations and clarifications of the phenomenon of stress
concentration, and increasing the load capacity of parts using
prior elasto-plastic deformation and surface plastic deformation.
The second part examines machine elements and units. Topics include
load capacity calculations of interference fit connections under
bending, new considerations about the role of the interference fit
in key joints, a detailed examination of bolts loaded by
eccentrically applied tension forces, resistance of cylindrical
roller bearings to axial displacement under load, and a new
approach to the choice of fits for rolling contact bearings. The
third section addresses strength calculations and life prediction
of machine parts. It includes information on the phenomena of
static strength and fatigue; correlation between calculated and
real strength and safety factors; and error migration.

From the Physiology of Machines to the Anatomy of Machines An
offshoot stemming from the author's previous book detailing the
makeup and composition of a machine, Power Mechanisms of Rotational
and Cyclic Motions provides an in-depth analysis of machine
structure and operation. An important reference for practicing
mechanical engineers, this book presents the kinematic diagrams of
driving mechanisms in detail, analyzes their motion characteristics
and efficiency, and addresses the lubricating problems that impact
the reliability and operating life of machines. The diagrammatic
representation of mechanisms is accompanied by examples of their
general and detailed design, main geometry calculations, and
recommendations for an approximate evaluation of principal
dimensions. The authors consider the main stages of design,
including the choice and analysis of kinematic diagrams,
preliminary sizing, embodiment, and the design and dimensioning of
specific elements including gears, shafts, bearings, springs, cams,
fasteners, and others. A pivotal work, the book contains details of
design that include: Analysis of diagrams of mechanisms (for their
kinematic effects and efficiency) Rough dimensioning of the main
elements Examples of the design of mechanisms and their elements
(with relevant calculations of geometry and for strength) Design of
specific subassemblies and parts (including their materials and
heat treatment) Choice and design of lubrication systems Intended
for engineering postgraduates, engineers, and designers of
machines, Power Mechanisms of Rotational and Cyclic Motions also
describes the main metals used in machinery and their mechanical
characteristics and provides expressions for strength calculation.
Covering a wide range of mechanisms, it contains numerous examples
of design of mechanisms and accompanying calculations and design
hints based on the authors' vast experience.
