A metal specimen with a square cross-sectional area having a gauge length of 50.0 mm is pulled in tension.
If its width at the point of fracture is 5 mm and fractured gauge length is 75 mm. Calculate the ductility in
terms of:
a) percent elongation
b) percent reduction in area
(Assume that its original width is 9 mm.)
