Experiment Two- Torsional test Experiment Two (2) Torsional testing of Circular Shafts Introduction: Torsion occurs when any shaft is subjected to a torque. This is true whether the shaft is rotating (such as drive shafts on engines, motors and turbines) or stationary (such as with a bolt or screw).Torsion of a Circular Shaft. A circular shaft, when subjected to torsion, experiences a twisting action along its length due to the applied torque. This results in a shear stress that is distributed over the cross-section of the shaft. The torsional equation for a hollow circular shaft is given by:\[ \tau = \frac{T \cdot r}{J} \]where: This chapter focuses on the elementary theory of torsion. It describes the elastic torsion of various thin-walled closed and open sections, in addition to the shaft of solid circular cross section.This video throws light on Torsion in Circular Shafts. The topic is a part of the Strength of Materials course that is also known as the Mechanics of Solids .
