a three-volume work entitled, Wyklad
Elements& Mn zln, and written by Dr llaz Waclaw Mnszynski, Professor of
WZREal Engineering at the Technical Univereity of Warsaw. The work wus
published in Warsaw in 1949 by the Stowarzyszenie inzynierov Folskich Mechani-
kow (SIWI). There is a ,publisher " note in the second volume that the first
printing (four thousand copies) of Volume I was sold out 'within a few months
of relea e. Volume I contains chanters on materials and their properties;
welded joints; riveted fastenings; screwed fastenings; pipes and their sonnec-
tionp; valves; stuffing boxe . Volume II (searing Design) contains chapters on
plain bearings; ball and roller bearings; bearing housings (comprising heavy
machine frames); shafts and axes; couplings and clutches; brake . Volume III
(Drives) contains chanters on friction drives; flexible transmission; toothed
gears, kinematics; toothed gears, stress analysis; gear loxes. The author
states in his preface that the text covers the entire series of lectures on
the subject of machine design which are given at the Technical University ,af
Warsaw as well as supplementary technical information which could not be in-
cluded in the lectures. Pe tates further that a fourth volume is in prepara.-
tion (1949) which will treat of cams, transmission of motinn hv MORna .cv irer.
cranks, valve gears and vibration of shafts
2. The course in the Des. of Machine Elements at the Technical University of
Warsaw ff9q7 is taught in the second year and consists of four lecture hours
a week plus four or five comprehensive drafting problems per emester.
Mbezynski's text is adapted for use in the Xnropean system of engineering
training/ whereby the study of such specialized subjects as lifting machines,
boiler, team engines, steam turbines, and internal coP.N.usticn engines is
incorporated in the third, fourth, and fifth year curricula. In his text.
Moszynski present a variety of design solutions for a typical machine
element, consider tress,' analysis for various types of loading, and dis-
cusses allowable stresses and coefficients used in calculations and the
influence of the &ape of an object on casting processes and machining.

there is no existing US or UK text which treats
of the subject in the manner advocated by Moszynski. There are, of course,
various English textbooks on particular design problems, but none in which
these problems are assembled and studied in a detailed treatise on machine
elements. One will find, for example, many books written on the subject of
toothed gears, but the study of kinematics is usually confined to texts on
mechanics of machinery 9.nd the study of stress analysis to those dealing
with -machine design. Rotschercs Maschinenelemente, published in 1924 and
now 27:9517 out-of-date, is one of a few Oerman texts which use the same approach
to the subject as Moszynaki.
