Two previously undeformed cylindrical specimens of brass 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 16 and 11 mm, respectively. The second specimen, with an initial radius of 11 mm, must have the same deformed hardness as the first specimen. Calculate the second specimen's radius after deformation.
