Mechanical Design of Machine Elements by Graphical Methods

Description

This book covers designing of various machine elements and serves as a reference for mechanical designing of machine elements in academia and industry. It provides information on designing approaches and several examples and problems, enabling readers to make all of their required calculations for their specific mechanical design or fabrication tasks by using the book’s plots (graphs), instead of complicated formulas.
