Problem 7.23 Your answer is partially correct. Try again. Consider the brass alloy for which the stress-strain behavior is shown in the Animated Figure 7.12. A cylindrical specimen of this material 10.1 mm (0.3976 in.) in diameter and 98.8 mm (3.890 in.) long is pulled in tension with a force of 10200 N (2293 lbr). If it ls known that this alloy has a value for Polsson's ratio of 0.35, compute (a)...

A brass alloy is known to have a yield strength of 275 MPa (40,000 psi), a tensile strength of 380 MPa (55,000 psi), and an elastic modulus of 103 GPa (15.0×106 psi). A cylindrical specimen of this alloy 9.0 mm (0.35 in.) in diameter and 245 mm (9.65 in.) long is stressed in tension and found to elongate 9.0 mm (0.35 in.). A) What is the yield strain? B) What is the test strain?
