Two previously undeformed cylindrical specimens of an alloy areto be strain hardened by reducing their cross-sectional areas(while maintaining their circular cross sections). For onespecimen, the initial and deformed radii are 16 mm and 12 mm,respectively. The second specimen, with an initial radius of 11 mm,must have the same deformed hardness as the first specimen; computethe second specimen's radius, in mm, after deformation.
