This new edition of what is a very successful Pocket Book has been substantially revised to take account of the most recently introduced standards and the newest technology. Always with the emphasis on current engineering practice, this is an exhaustive collection of useful data supported by clear accounts of the fundamental principles, essential for both the modern mechanical engineer and the student of mechanical engineering. This mass of information is rendered easily accessible by division into four main parts - maths and science, design data, materials and cutting tools - which are in turn divided into smaller topic areas. A well laid-out contents and index help the reader find their way around.
