Question: In Problem, fracture occurs at a gage length of 2.92 in
(a) Determine the percent elongation.
(b) If the specimen necked to an area = 0.25 in2, determine the percent reduction in area.
Problem: A test specimen in a tensile test has a gage length of 2.0 in and an area =0,5 in2. During the test the 147.01 mm, (5)27,578 N at 153.00 With; and (026;462 N at 160.10.mm. The maximum load is 28,913 N and the final data point occurred immediately prior to failure specimen yields under a load of 32,000 lb. The cor-responding gage length = 2.0083 in. This is the 0.2% yield point. The maximum load = 60,000 lb is reached at a gage length = 2.60 in. Determine
(a) yield strength,
(b) modulus of elasticity, and
(c) tensile strength.
