What is Torsion ?

Torsion is the state of strain in a material that has been twisted by an applied torque. Torsion develops shear stresses and is equivalent to tension and compression at right angles.

What is the reason for Torsion in beam?

Torsion in beams arises generally from the action of shear loads whose points of application do not coincide with the shear center of the beam section.
