Part D-Permanent elongation of the specimen if the specimen is loaded until its nominal stress value reaches 65 ksi, determine the increase in gauge length after it is unloaded. The strain at 65 ksis 06 in. fin. Express your answer to four significant figures and include the appropriate units. View Available Hint(s) Permanent elongation=6 → % ?
