\ Problem 1 ( 7 points): The material for the
50mm-long cylindrical specimen with a 2
0mmdiameter has the stress-strain diagram shown. (a) (2 points) If a force
P=100kNis applied and released, determine the elongation of the specimen in diameter of 0 release. (b) (2 points) When the force
P=100kNis applied, a (c) (3 points) If a force
P=150kmis observed. What is the material's Poisson rathe elongation of the specimen befor applied instead and then released, determine the elon and after release.
