Generally two types of stresses are induced in a shaft. 

1. Torsional (Shear) stresses due to transmission of torque. 

2. Bending stresses due to weight of pulley, gear etc mounted on shaft. 

A circular shaft is said to be in a state of pure torsion when it is subjected to torque only, without being acted upon by any bending moment or axial force. 

OR; if the shaft is subjected to two opposite turning moment it is said to be in pure torsion. and it will exhibit the tendency of shearing off at every cross-section which is perpendicular to longitudinal axis.
