Homework Statement


A specimen with an original length of 165 mm is subjected to a tensile load of 4500 N until it breaks. It’s final length is 202 mm. Calculate the specimen’s ductility in terms of percent elongation to break.

Homework Equations


((Lf - Lo) / Lo) * 100 = %EL

The Attempt at a Solution


( (202-165) / 165) * 100 = 22.42 %

I feel like I am completely wrong or still missing something. Is this percentage the specimen's ductility and the percent elongation?

Thank you,
Douglas

Thank you, sir.

I keep thinking of ductility as a separate calculation but it turns out this calculation covered it.
