    Unit of torsional stiffness is Nm / rad,
    it cant be say as Nm?
    as radian have no dimension.

    - Torsional rigidity: It is defined as the product of modulus of rigidity and polar moment of inertia.

    K = G x J

    - S.I. unit of torsional rigidity is Nm2

    - Nm/radian is the S.I. unit of torsional stiffness. Torsional stiffness is defined as the torque required to produce unit angle of twist.
