Textbook Question
Chapter 10, Problem 10.21SP
A 12.5-mm-diameter steel rod was subjected to a tension test. After rupture, it was determined that the original 50-mm gage length had elongated to 60.7 mm. The minimum diameter at the fracture point was measured to be 10.7 mm. Compute the percent elongation and percent reduction in area.
