QUESTION
The following data were obtained during a tension test of a low carbon steel specimen
having a gauge length of 100 mm.
At the point where the stress strain curve deviated from linearity, the load was 35KN, the
gauge length was 102.5 mm and the diameter of the specimen was 1.6 mm. Before necking
began, loads of 45 KN and 55 KN produced gauge lengths of 103.4 mm and 107.7 mm
respectively.
Calculate
(a) The Modulus of elasticity
(b) The Strainhardening exponent
