Question: Two identical specimens 10 mm in diameter and with test sections 25 mm long are made of 1112 steel. One is in the as-received condition

Two identical specimens 10 mm in diameter and with test sections 25 mm long are made of 1112 steel. One is in the as-received condition and the other is annealed. What will be the true strain when necking begins, and what will be the elongation of these samples at that instant? What is the ultimate tensile strength for these samples?
