A tensile test is performed on a linear elastic material using a cylindrical bar of diameter 5 mm and gauge length 55 mm. An axial tensile force of 960 N is applied to the test specimen and a corresponding extension of 0.56 mm is recorded by the extensometer. Assuming that the Poisson's ratio is 0.3, calculate the modulus of rigidity (also known as the shear modulus), G, for this material. Enter your value in units of GPa to one decimal...
