Final answer:
The percent elongation of the weld tension test specimen is 10.40%, which is calculated using the elongation formula and substituting the given initial and final gauge lengths.
Step-by-step explanation:
To calculate the percent elongation for the weld tension test specimen, you need to use the formula for percent elongation:
Percent Elongation = ((Final Gauge Length - Original Length) / Original Length) x 100%
Plugging in the values for this question:
Percent Elongation = ((2.208 in - 2.000 in) / 2.000 in) x 100%
Percent Elongation = (0.208 in / 2.000 in) x 100%
Percent Elongation = 0.104 x 100%
Percent Elongation = 10.40%. The correct answer is c) 10.40%.
