The science of adhesive joints

BOOK NOTES THE SCIENCE OF ADHESIVE JOINTS, by J. J. Bikerman. 258 pages, diagrams, 5: X 8 in. New York, Academic Press Inc., 1961. Price, $8.00. In this monograph, the author stresses the science of adhesive joints (which he calls of adhints), rather than the formulation specific adhesives. After an introductory chapter explaining the terms used in bonding, the author defines adhesive joints and devotes one chapter to the formation of such joints including wetting, measurement of contact angles, and pretreatment of adherent surfaces. Four chapters cover, respectively, tack, setting, final strength of adhints, and stresses in Experimental strength of adhints adhints. is dealt with in Chapter 8; Chapter 9 describes a few of the less common tests employed in adjudging adhints. The final chapter is a short summary for the “nractical” man seeking to find out what is wrong with a weak joint. PROGRESS IN CRYOGENICS, edited by K. Mendelssohn. Volume 3, 173 pages, diagrams, plates, 6 X 94 in. New York, Academic Press Inc., 1961. Price, $8.00. Volume 3 of this series contains the following papers : “Helium Liquefiers,” by A. J. Croft; “Low Temperature Heat Exchangers,” by A. G. Lenfestey; “Novel Refrigeration Cycles and Devices,” by W. E. Gifford; “Cryogenic Rocket Propellants,” by I. E. Smith ; “Paramagnetic Substances for Nuclear Orientation,” by R. P. Hudson; and “Dynamic Nuclear Orientation,” by C. D. Jeffries. DYNAMICS: VOLUME 2 OF ANALYTICAL ELEMENTSOF MECHANICS,by Thomas R. Kane. 324 pages, diagrams, 5: X 82 in. New York, Academic Press Inc., 1961. Price, $6.25. Volume 2 of this undergraduate text in classical mechanics deals with dynamics. Stressing kinematics and the theory of moments and products of inertia, the author begins his discussion with a chapter on the differentiation of vectors. Chapter 2, on kine416

matics, deals with rates of change of orientation, angular velocity and acceleration, relative velocity and acceleration, and absolute velocity and acceleration. Chapter 3 discusses second moments of a point, a set of points, curves, surfaces and solids, and sets of particles. The fourth and final chapter is on the laws of motion. Twelve sets of problems, with answers, appear at the end of the book. PLASTICS IN NUCLEAR James 0. Turner. 134 5 X 73 in. New York, ing Corp., 1961. Price,

ENGINEERING, by pages, illustrations, Reinhold Publish$5.50.

This book describes the ways in which plastics are made to serve the nuclear scientist and engineer. It is intended for designers and operating personnel concerned with Bevatrons, reactors, bubble chambers and other equipment used in nuclear engineering. The book covers applications of plastics to the measurement of radiation, radiation protection, high-voltage service, low-voltage service, magnets, high-vacuum apparatus, and optical apparatus. Mechanical and thermal uses of plastics are dealt with, and a final chapter covers effects of radiation on plastics. FLUID MECHANICS, by Richard H. F. Pao. 484 pages, diagrams, 6 X 9 in. New York, John Wiley & Sons, Inc., 1961. Price, $7.50. An introductory text in fluid mechanics, this new work emphasizes the concepts and principles of fluid motion that are common to applications in all branches of engineering. The author stresses physical concepts and uses rational approaches in developing the fundamental equations. After an introductory chapter, ten chapters cover: fluid statics, fluid kinematics, fluid dynamics, fluid viscosity and flow of real fluids, dimensional analysis and model similitude, flow of incompressible fluids in closed conduits, fluid compressibility and compressible flow, fluid flow about immersed bodies, dynamic lift, and flow of liquids in open channels.
