An unspecified pure bending moment is used to bend an aluminium rod of radius 2.5 mm elastically into a circular ring of radius 2 m. If the same bending moment is used to bend elastically a copper rod of radius 2 mm, the radius of the resulting ring (in m) is (Elastic modulus of aluminium is 70 GPa and elastic modulus of copper is 120 GPa).
