Extracted text: There are two previously undeformed cylindrical specimens of Aluminum alloyithat are strain hardened by reducing their cross-sectional areas (while maintaining the original cross-sectional shape). If one specimen's initial and deformed radii are 20 mm and 16 mm, respectively, calculate and choose the initial radius of the other specimen if its radius after deformation is 18.4 mm and two specimens have the same deformed hardness.
