Question

Can someone help me with this materials problem?

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) the specimen elongation, (b) the reduction in specimen diameter. Note: because the diameter decreases, enter a minus sign in your answer.
