A shaft subjected to torsion experiences a pure shear stress τ on ...
That is correct. Torsion is a type of mechanical loading where a shaft or other solid object is subjected to twisting forces. In torsion, the applied torque creates a shear stress in the material, causing it to deform. This shear stress is referred to as pure shear stress because it is the only type of stress that occurs in torsion, unlike other types of loading such as bending or axial loading which result in a combination of shear stress, normal stress, and axial stress.
