brass alloy has a yield strength of 240 mpa, a tensile strength of 310 mpa, and a modulus of elasticity of 110 gpa. a cylindrical specimen of this alloy 15.2 mm in diameter and 380 mm long is stressed in tension and found to elongate 1.9 mm. is it possible to compute the magnitude of the load that is necessary to produce this change in length using only the information given? if so, calculate the load. if not explain why and suggest what additional information is needed to complete the calculation.
