LRULIpLS HHOlm this work may be reproduced by instructors for distribution on a not-for profit basis fot testing or instructional purposes on to students enrolled in courses for which the textbook has been adopted. Any other reproduction or transiation of this work beyond that permitted by Sections 107 or 108 of the 1976 United States Coppright Aof without the permission of the copyright owner is unlawful P3.12 The complete stress-strain diagram for a particular stainless steel alloy is shown in Figure P3.12a/13a. This diagram has been enlarged in Figure P3.12b/13b to show in more detail the linear portion of the stress-strain diagram. A rod made from this material is initially 800 mm long at a temperature of 20°C. After a tension force is applied to the rod and the temperature is increased by 200°C, the length of the rod is 804 mm. Determine the stress in the rod, and state whether the elongation in the rod is elastic or inelastic. Assume the coefficient of thermal expansion for this material is 18x10/ c. 160 20 80 2 80 40 40 Enlargement of the linear portion 0.0 0.002 0.004 0.006 0.008 0.010 0.00.020 0.040 0.0600.080 0.1000.120 Strain (in /in.)
