Mensuration for Sheet Metal Workers – As Applied in Working Ordinary Problems in Shop Practice 

This vintage book contains a comprehensive guide to the problems of geometry and measurement encountered by sheet metal workers. It comprises a series of examples that show the working out of the circumferences, areas, and capacities for various shapes-an exercise that is intended to enable the student to deal with any ordinary problem that may arise in the workshop. Contents include: ‘Length of Material Required for a Round Pipe’, ‘Amount of Material for a Square Pipe’, ‘Length of Perimeter of a Hexagon’, ‘Square and Circular Sections of Pipe of given Dimensions’, ‘Length of Side of a Square to be Enclosed by a Given Circle’, ‘Length of Arc when Angle and Radius are Known’, ‘Amount of Material for an Ellipse when Length and Width are Given’, et cetera. Many vintage books such as this are increasingly scarce and expensive. We are republishing this volume now in an affordable, modern edition complete with a specially commissioned new introduction on metal work. This book was first published in 1913.
