A cylindrical specimen of a hypothetical metal alloy is stressed in compression. If its original and final diameters are 16.403 and 16.424 mm, respectively, and its final length is 75.4 mm, calculate its original length if the deformation is totally elastic. The elastic and shear moduli for this alloy are 101 GPa and 43.4 GPa, respectively. (Hint: G = E 2(1+ν) )
