Almost every device that industrialized people use involves a rotating part of some sort, says mechanical engineer Piotrowski, and easily half of the problems with rotating equipment he has seen over the past three decades have had something to do with misaligned shafts. Yet information about shaft alignment is not taught in any high schools or junior colleges or any courses for engineers, mechanics, millwrights, pipe fitters, or electricians. The third edition is rearranged to reflect feedback on the 1986 and 1996 editions. It includes many photographs and drawings illustrating the methods he describes for measuring and correcting alignment. Annotation ©2007 Book News, Inc., Portland, OR (booknews.com)
