An alloy has a yield strength of 41 ksi, a tensile strength of 57 ksi, and an elastic modulus of 16 * 106 psi. A cylindrical specimen of this alloy 0.5 in. in diameter and 10 in. long is stressed in tension and found to elongate 0.3 in. On the basis of the information given, is it possible to compute the magnitude of the load that is necessary to produce this change in length
