A cylindrical bar of metal having a diameter of (4.740x10^0) mm and a length of (9.9406x10^2) mm is deformed elastically in tension with a force of (1.281x10^4) N.
Given that the elastic modulus and Poisson's ratio of the metal are (1.0596x10^2) GPa and (3.31x10^-1) , respectively, determine the change in diameter of the specimen (in mm). Indicate an increase in diameter with a positive number and a decrease with a negative number.
