A torsion member is made of steel 17.67cm in diameter. To save mass it is proposed to replace it with a hollow bar of the same type of steel with a 10.16cm diameter hole through its center. What should the outside diameter hollow bar be to provide the same torsional stiffness? Use two decimal places
