This eighth volume of Reed's Marine Engineering Series prepares students for the Department of Transport Certificates of Competency in General Engineering Knowledge. It also covers the syllabus for Engineer Cadet courses in the subject. The syllabus and principles involved are virtually the same for all examinations but questions set in Class One require the most detailed answers. The book follows the same pattern as the other volumes in this series which has proved so successful: emphasis on basic principles, extensive illustrations, worked examples included in the text, practice examples at the end of each chapter and specimen exam questions at the end.
