Torsion
CHAPTER OBJECTIVES
Shafts of circular section are generally used for power transmission from prime mover (such as engine, electric motor) to operating machines such as lathe, shaper or any manufacturing machine. In this chapter students are made to learn about the development of shear stress and angular twist in a shaft or a combination of shafts due to twisting moment applied on them. Then, the shafts are connected to gears and pulleys with the help of keys and how stresses are developed in the keys. Moreover, students will learn about the variation of stress along the radius and angular twist along the length of the shafts.
Introduction
Shafts are generally made of ductile materials like mild steel. Due to the application of ...
