Two previously undeformed cylindrical specimens of an alloy are to be strain hardened by reducing their cross-sectional areas (while maintaining their circular cross sections). For one specimen, the initial and deformed radii are listed above as radius 1 and radius 2. The second specimen, has the initial radius listed, must have the same deformed hardness as the first specimen; compute the second specimen's radius, in mm, after deformation
