Essentials of Machine

Elements and Design



Book description

​​​​The book, Essentials of machine elements and design is packaged to contribute to design knowledge of machine element and basic rudiments of production functions. This book gave wider and adequate background knowledge of principles and practice relevant to machine design and mechanical production at all levels of training in the university, polytechnic and colleges.

 This knowledge will be demonstrated by completion of assignment sheets and selected activities with a minimum of 85 percent accuracy.
