Hooke's Law previous l 1 of 3 l next Hooke's Law Learning Goal: To use Hooke's law to determine the modulus of elasticity of a material from a conventional stress-strain diagram and use the 0.2% offset method to find the yield strength, as well as to determine the approximate amount of elastic recovery and increase in gauge length in the specimen under certain loading Conditions. A tension test was conducted on a steel alloy having an original diameter of 0.5 in and a gauge length of 2.0 in A conventional stress-strain diagram was constructed from the results of the test and is shown below. G (0.26, 55) F (0.0028, 44) 30 10 E (0,0) E (in/in) 0.04 0.08 0.12 0.16 0.20 0.24 0.28 8:26 PM Search... 2/8/2017Explanation / Answer
Amount of elastic recovery = strain corresponding to yield strength - proof strain
= 0.0045 - 0.0020
= 0.0025 in/in
