A cylindrical specimen of brass that has a diameter of 15 mm, a tensile modulus of 120 GPa, and a Poisson’s ratio of 0.30 is pulled in tension with force of 50,000 N. If the deformation is totally elastic, what is the approximate strain experienced by the specimen?
A cylindrical specimen of brass that has a diameter of 21 mm, a tensile modulus of 122 GPa, and a Poisson’s ratio of 0.37 is pulled in tension with force of 38704 N. If the deformation is totally elastic, what is the strain experienced by the specimen?
An unknown specimen with an initial diameter of 5.25 mm experiences a reduction in diameter to 4.50 mm under a tensile load of 250 N. Calculate the engineering stress, engineering strain, true stress, and true strain at this load. Assume that the deformation is uniform throughout the entire sample, and that the volume of the sample remains constant when being pulled in tension.
