I A tensile test specimen having rectangular cross section with a width of 19.23mm and a thickness of 7.98mm will be tested according to standard. a) Please calculate a proportional first length, to mark on the specimen prior to test. b) After test, your specimen broken like in the following figure. (necking is not just in the middle of the marked length!!!). How do you determine the length after fracture. c) Please calculate A (percentage elongation after fracture) +1 +""""" "" Length of each division (after fracture) is given on the specimen 7,0
