Problem 1.5-8 A steel bar of length 2.5 m with a square cross section 100 mm on each side is subjected to an axial tensile force of 1300 kN (see figure). Assume that E 5 200 GPa and v 5 0.3. Determine the increase in volume of the bar. 24 CHAPTER 1 Tension, Compression, and Shear 100 mm 100 mm 1300 kN 2.5 m 1300 kN Solution 1.5-8 Square bar in tension Find increase in volume.
