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...

A flat 1018 steel sample was tested in a tensile machine. Sample dimensions are width = 0.425 inch, thickness = 0.175 inch, original gauge length = 3.45 inch. The sample shows yielding when 3300 lb force is applied with a corresponding change in length of 0.06 inch. From the data, the greatest force applied during testing was 4500 lbs and the sample had elongated by total of 0.5 inch. At fracture, the force applied to the sample decreased to 3000...
