Textile Mechanics and Calculations

Description

Textile Mechanics and Calculations is written with exhaustive information on the mechanical elements used in power transmission and textile equipment and machines. For the first time, an attempt has been made to include all the theoretical data for each topic with solved numerical examples. The special feature of this book is the inclusion of a number of cams and tappets and stepped pulley construction found in engineering and textile applications. The book also has the displacement, velocity and acceleration diagrams with textile examples. In addition to mechanics of spinning, the book also has details of the mechanics of the weaving process with several derivations.  Read more...
