Atensile test was made on a tensile specimen, with a cylindrical gage section which had a diameter of 10 mm, and a length of 40 mm. after fracture, the length of the gage section was found to be 50 mm, the reduction in area 90 percent, and the load at fracture 1000 n. compute: a) b) c) d) the specimen elongation. the engineering fracture stress. the true fracture stress. the true strain at the neck. note: the reduction in area is defined as the initial area, minus the final area, divided by the initial area
