A cylindrical bar of metal having a diameter of 18.8 mm (A=278 mm^2) and a length of 198 mm is deformed elastically in tension with a force of 49400 N. Given that the elastic modulus and Poisson's ratio of the metal are 67.1 GPa and 0.34, respectively, determine the amount by which this specimen will elongate (in mm) in the direction of the applied stress.
