Calculate the resulting strain. . 7.6 Consider a cylindrical titanium wire 3.0 mm in diameter and 2.5x104 mm long. Calculate its elongation when a load of 500 N is applied. Assume that the deformation is totally elastic. 7.10 Figure 7.34 shows, for a gray cast iron, the tensile engineering stress–strain curve in the elastic region. Determine (a) the secant modulus taken to 35 MPa, and (b) the tangent modulus taken from the origin. 3 Introduction to Materials Science 7.17 A cylindrical specimen of a hypothetical metal alloy is stressed in compression. If its original and final diameters are 20.000 and 20.025 mm, respectively, and its final length is 74.96 mm, compute its original length if the deformation is totally elastic. The elastic and shear moduli for this alloy the deformation is totally elastic....
